Subject: [PATCH 2/2] staging: media: atomisp2: Replace kfree()/vfree() with kvfree()
Date: Fri, 7 Jul 2017 20:41:02 -0400	[thread overview]
Message-ID: <20170708004102.GA27161@amitoj-Inspiron-3542> (raw)

Conditionally calling kfree()/vfree() can be replaced by a call to 
kvfree() which handles both kmalloced memory and vmalloced memory. 
Consequently removed an unnecessary comment.

The Coccinelle semantic patch used to make the change is as follows:
//<smpl>
@@
expression a;
@@
- if(...) { vfree(a); }	
- else { kfree(a); }
+ kvfree(a);
@@
expression a;
@@
- if(...) { kfree(a); }	
- else { vfree(a); }
+ kvfree(a);
// </smpl>
