So imo for more easier telling apart of these too I think consistently using the short form for booleans, and consistently using the more explicit long form for errno checks is a Very Good Pattern :-) Cheers, Daniel > > Christian. > > > > > > Alex > > > > > > On Wed, Sep 9, 2020 at 9:21 AM Christian König <christian.koenig@xxxxxxx> wrote: > > > > Acked-by: Christian König <christian.koenig@xxxxxxx> for the series. > > > > > > > > Am 09.09.20 um 15:07 schrieb Zheng Bin: > > > > > Zheng Bin (8): > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in gfx_v9_0.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in gfx_v10_0.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in sdma_v5_0.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in sdma_v5_2.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in si.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in uvd_v6_0.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in > > > > > amdgpu_atpx_handler.c > > > > > drm/amd/amdgpu: fix comparison pointer to bool warning in sdma_v4_0.c > > > > > > > > > > drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c | 4 ++-- > > > > > drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c | 2 +- > > > > > drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c | 2 +- > > > > > drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c | 4 ++-- > > > > > drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c | 2 +- > > > > > drivers/gpu/drm/amd/amdgpu/sdma_v5_2.c | 2 +- > > > > > drivers/gpu/drm/amd/amdgpu/si.c | 2 +- > > > > > drivers/gpu/drm/amd/amdgpu/uvd_v6_0.c | 4 ++-- > > > > > 8 files changed, 11 insertions(+), 11 deletions(-) > > > > > > > > > > -- > > > > > 2.26.0.106.g9fadedd > > > > > > > > > _______________________________________________ > > > > amd-gfx mailing list > > > > amd-gfx@xxxxxxxxxxxxxxxxxxxxx > > > > https://lists.freedesktop.org/mailman/listinfo/amd-gfx > > > _______________________________________________ > > > dri-devel mailing list > > > dri-devel@xxxxxxxxxxxxxxxxxxxxx > > > https://lists.freedesktop.org/mailman/listinfo/dri-devel > > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
