Subject: staging: bcm2835-audio: don't initialize memory twice
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=588e7ac5b1cbcb4bda5d26c0757c0a52d5f43bfd;p=openwrt%2Fstaging%2Fblogic.git

staging: bcm2835-audio: don't initialize memory twice

The memory is being allocated with devres_alloc(), wich ultimately uses
__GFP_ZERO to call kmalloc. We don't need to zero the memory area again
in bcm2835-audio.
