Vissarionov <gremlin@xxxxxxxxxxxx> Date: Tue Jan 17 14:15:23 2023 +0300 ALSA: hda/ca0132: minor fix for allocation size [ Upstream commit 3ee0fe7fa39b14d1cea455b7041f2df933bd97d2 ] Although the "dma_chan" pointer occupies more or equal space compared to "*dma_chan", the allocation size should use the size of variable itself.
