From 17b6753ff08bc47f50da09f5185849172c598315 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 4 Dec 2019 16:53:06 -0800 Subject: lib/test_bitmap: force argument of bitmap_parselist_user() to proper address space Patch series "gpio: pca953x: Convert to bitmap (extended) API", v2. While converting gpio-pca953x driver to bitmap API, I noticed that we have no function to replace bits. So, that's how patch 7 appears. First 6 patches are preparatory of the test suite (including some warning fixes, etc). Patches 8-9 are preparatory for the GPIO driver to be easier converted to bitmap API, conversion to which happens in patch 10. Patch 11 contains simple indentation fixes. This patch (of 11): Sparse complains: lib/test_bitmap.c:345:58: warning: incorrect type in argument 1 (different address spaces) lib/test_bitmap.c:345:58: expected char const [noderef] *ubuf lib/test_bitmap.c:345:58: got char const *const in Force argument of bitmap_parselist_user() to proper address space.
