2019-05-24media: venus: firmware: fix leaked of_node referencesWen Yang
The call to of_parse_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: drivers/media/platform/qcom/venus/firmware.c:90:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 82, but without a corresponding object release within this function. drivers/media/platform/qcom/venus/firmware.c:94:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 82, but without a corresponding object release within this function. drivers/media/platform/qcom/venus/firmware.c:128:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 82, but without a corresponding object release within this function.

2019-05-24media: remove redundant 'default n' from Kconfig-sBartlomiej Zolnierkiewicz
'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

2019-05-23media: Kconfig: allow to select drivers if EMBEDDEDStefan Agner
Embedded systems often connect to sensors or other multimedia subdevices directly. Currently, to be able to select such a subdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto- select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT). This is inconvenient as the ancillary drivers for a particular device then need to be selected manually. Allow to select drivers manually while keeping the auto-select feature in case EXPERT (selected by EMBEDDED) is enabled.

buf->size is an unsigned long; casting that to int will lead to an overflow if buf->size exceeds INT_MAX. Fix this by changing the type to unsigned long instead. This is possible as the buf->size is always aligned to PAGE_SIZE, and therefore the size will never have values lesser than 0.

Some displays pull down the HPD when in standby, but CEC is still active and the display can be woken up by sending an Image View On or Text View On CEC command. The CEC specification doesn't tell you what the initiator should be for such a command (without a HPD it's unclear if the CEC adapter can claim a logical address).

2019-05-23media: cec-gpio: use disable/enable_irqHans Verkuil
Due to limitations in gpiolib it was impossible to disable the interrupt of an input gpio and then switch it to gpio output and drive it. The only way to achieve that was to free the interrupt first, then switch the direction. When going back to gpio input and using interrupts to read the gpio pin you had to request the irq again. This limitation was lifted in gpiolib in kernel 4.20, but the cec-gpio driver was still using the old workaround implementation. This patch updates the cec-gpio driver to just enable and disable the irq. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
