[PATCH] drm/amdgpu: Fix missing parameter descriptions in ih_v7_0.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Rectifies kdoc warnings related to the 'ih' parameter in the
'ih_v7_0_get_wptr', 'ih_v7_0_irq_rearm', and 'ih_v7_0_set_rptr'
functions within the 'ih_v7_0.c' file.

Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/ih_v7_0.c:392: warning: Function parameter or member 'ih' not described in 'ih_v7_0_get_wptr'
drivers/gpu/drm/amd/amdgpu/ih_v7_0.c:432: warning: Function parameter or member 'ih' not described in 'ih_v7_0_irq_rearm'
drivers/gpu/drm/amd/amdgpu/ih_v7_0.c:458: warning: Function parameter or member 'ih' not described in 'ih_v7_0_set_rptr'
