[PATCH v2] Staging: rtl8723bs: core: rtw_cmd: Remove cast to pointer types in kfree
From: Srishti Sharma
Date: Sat Oct 07 2017 - 16:33:36 EST
The cast to pointer types in kfree is not needed and can be dropped.
This was done using the following semantic patch by coccinelle,
except kfree((unsigned char*) pcmd->parmbuf) which was transformed by
hand because coccinelle didn't have enough type information.
@r@
type T,P;
T* x;
@@
kfree(
-(P *)
x )
Signed-off-by: Srishti Sharma <srishtishar@xxxxxxxxx>

Changes in v2:
-Do transformation left out by coccinelle
-Improve commit message
