Subject: [PATCH 1547/2940] drm/amdgpu/gfx_v8_0: Mark expected switch
fall-through
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c: In function ‘gfx_v8_0_tiling_mode_table_init’:
./include/linux/device.h:1487:2: warning: this statement may fall through [-Wimplicit-fallthrough=]
_dev_warn(dev, dev_fmt(fmt), ##__VA_ARGS__)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:3236:3: note: in expansion of macro ‘dev_warn’
dev_warn(adev->dev,
^~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c:3240:2: note: here
case CHIP_CARRIZO:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
