[PATCH] ALSA: hda/ca0132: minor fix for allocation size

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

 



Although the "dma_chan" pointer occupies more or equal space compared
to "*dma_chan", the allocation size should use the size of variable
itself.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
