Subject: lib/test_bitmap: force argument of bitmap_parselist_user() to proper
address space
Git-commit: 17b6753ff08bc47f50da09f5185849172c598315
Patch-mainline: v5.5-rc1
References: jsc#SLE-15847
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] <asn:1> *ubuf
lib/test_bitmap.c:345:58: got char const *const in
Force argument of bitmap_parselist_user() to proper address space.
