[PATCH] drm/msm: Fix an error handling path 'msm_drm_init()'

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

 



If this memory allocation fails, we have to go through the error handling
path to perform some clean-up, as already done in other other paths of
this function.

Fixes: db735fc4036b ("drm/msm: Set dma maximum segment size for mdss")
