2020-07-10fbdev: sm712fb: set error code in probeEvgeny Novikov
If smtcfb_pci_probe() does not detect a valid chip it cleans up everything and returns 0. This can result in various bad things later. The patch sets the error code on the corresponding path.

2020-07-10fbdev: da8xx-fb: go to proper label on error handling paths in probeEvgeny Novikov
fb_probe() can successfully allocate a new frame buffer, but then fail to perform some operations with regulator. In these cases fb_probe() goes to label err_pm_runtime_disable where the frame buffer is not released. The patch makes fb_probe() to go to label err_release_fb on corresponding error handling paths.

The drm/omap driver was fixed to correct an issue where using a divider of 32 breaks the DSS despite the TRM stating 32 is a valid number. Through experimentation, it appears that 31 works, and it is consistent with the value used by the drm/omap driver. This patch fixes the divider for fbdev driver instead of the drm.

2020-07-10video: fbdev: neofb: fix memory leak in neo_scan_monitor()Evgeny Novikov
neofb_probe() calls neo_scan_monitor() that can successfully allocate a memory for info->monspecs.modedb and proceed to case 0x03. There it does not free the memory and returns -1. neofb_probe() goes to label err_scan_monitor, thus, it does not free this memory through calling fb_destroy_modedb() as well. We can not go to label err_init_hw since neo_scan_monitor() can fail during memory allocation. So, the patch frees the memory directly for case 0x03.

2020-06-09mm: don't include asm/pgtable.h if linux/mm.h is already includedMike Rapoport
Patch series "mm: consolidate definitions of page table accessors", v2. The low level page table accessors (pXY_index(), pXY_offset()) are duplicated across all architectures and sometimes more than once. For instance, we have 31 definition of pgd_offset() for 25 supported architectures. Most of these definitions are actually identical and typically it boils down to, e.g. static inline unsigned long pmd_index(unsigned long address) { return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1); } static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address) { return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address); } These definitions can be shared among 90% of the arches provided XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined. For architectures that really need a custom version there is always possibility to override the generic version with the usual ifdefs magic. These patches introduce include/linux/pgtable.h that replaces include/asm-generic/pgtable.h and add the definitions of the page table accessors to the new header. This patch (of 12): The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the functions involving page table manipulations, e.g. pte_alloc() and pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h> in the files that include <linux/mm.h>. The include statements in such cases are remove with a simple loop: for f in $(git grep -l "include <linux/mm.h>") ; do sed -i -e '/include <asm\/pgtable.h>/ d' $f done Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Cain <bcain@codeaurora.org> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: "David S.

2020-05-31video: fbdev: convert get_user_pages() --> pin_user_pages()John Hubbard
This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA), using the categorization from [1]. That means that it's time to convert the get_user_pages*() + put_page() calls to pin_user_pages*() + unpin_user_pages() calls. There is some helpful background in [2]: basically, this is a small part of fixing a long-standing disconnect between pinning pages, and file systems' use of those pages.

2020-05-31video: fbdev: fix error handling for get_user_pages_fast()John Hubbard
Dealing with the return value of get_user_pages*() variants has a few classic pitfalls, and this driver found one of them: the return value might be zero, positive, or -errno. And if positive, it might be fewer pages than were requested. And if fewer pages than requested, then the caller should return (via put_page()) the pages that *were* pinned. This driver was doing that *except* that it had a problem with the -errno case, which was being stored in an unsigned int, and which would case an interesting mess if it ever happened: nr_pages would be interpreted as a spectacularly huge unsigned value, rather than a small negative value. Also, it was unnecessarily overriding a potentially informative -errno, with -EINVAL, in some cases. Instead: clamp the nr_pages to zero or positive, so that the error handling works. And return the -errno value from get_user_pages*(), unchanged, if we get one. And explain this with comments, seeing as how it is error-prone.
