V2: somehow managed to insert exactly the same line being removed
so this time actually do the intended kmalloc->kzalloc replacement
Found by coccinelle script (relaxed version of
scripts/coccinelle/api/alloc/kzalloc-simple.cocci)
Patch was compile tested with: x86_64_defconfig
CONFIG_SND_PCM_OSS=y
Patch is against linux-next (localversion-next is -next-20150518)
