lib/bitmap: introduce bitmap_replace() helper

2019-12-05T03:44:14Z

In some drivers we want to have a single operation over bitmap which is an equivalent to: *dst = (*old & ~(*mask)) | (*new & *mask) Introduce bitmap_replace() helper for this.

lib/test_bitmap: fix comment about this file

2019-12-05T03:44:14Z

This test case file is about bitmap API, and not printf() facility.

lib/test_bitmap: move exp1 and exp2 upper for others to use

2019-12-05T03:44:14Z

Some test cases may re-use predefined exp1 and exp2 bitmaps. Move them upper in the file.

lib/test_bitmap: rename exp to exp1 to avoid ambiguous name

2019-12-05T03:44:14Z

One function is using exp as local variable. Avoid ambiguous naming by rename global one to exp1.

lib/test_bitmap: name EXP_BYTES properly

2019-12-05T03:44:14Z

EXP_BYTES has been wrongly named. It's a size of the exp array in bits. While here, go ahead and rename to EXP1_IN_BITS to avoid double renaming when exp will be renamed to exp1 in the next patch Link: http://lkml.kernel.org/r/20191022172922.61232-4-andriy.shevchenko@linux.intel.com Signed-off-by: Andy Shevchenko Acked-by: Linus Walleij Cc: Bartosz Golaszewski Cc: Geert Uytterhoeven Cc: Marek Vasut Cc: Rasmus Villemoes Cc: Thomas Petazzoni Cc: William Breathitt Gray Cc: Yury Norov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

lib/test_bitmap: force argument of bitmap_parselist_user() to proper address space

2019-12-05T03:44:14Z

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.

lib/test_bitmap.c: add for_each_set_clump8 test cases

2019-12-05T03:44:12Z

The introduction of the for_each_set_clump8 macro warrants test cases to verify the implementation. This patch adds test case checks for whether an out-of-bounds clump index is returned, a zero clump is returned, or the returned clump value differs from the expected clump value.
