Subject: [PATCH V4] staging: cxt1e1: replace OS_kmalloc/OS_kfree with
kzalloc/kfree
Replace OS_kmalloc/OS_kfree with kzalloc/kfree.
And also some allocation doesn't need to use GFP_DMA
so just use GFP_KERNEL.
c4_new() function is never called, remove it.
Signed-off-by: Daeseok Youn <daeseok.youn@...il.com>
---
V4: update patch description, OS_kmalloc should be replaced with
kzalloc for zeroed out the allocated data.
V3: replace kmalloc with kzalloc.
V2: fix subject and comment correctly.
It has some coding style issue. If this patch is merged,
I fix this issue with another patch.
