From 3608c66c2e6522952b4be219317b194ab27f4e78 Mon Sep 17 00:00:00 2001 From: Vivek Kutal Date: Tue, 16 Jun 2009 15:34:42 -0700 Subject: fbdev: *bfin*: drop unnecessary calls to memset The dma_alloc_* functions sets the memory to 0 before returning so there is no need to call memset after the allocation. Also no point in clearing the memory when disabling the buffer.
