Subject: [media] drivers/media/platform/mx2_emmaprp.c: adjust inconsistent IS_ERR and PTR_ERR
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9f9831a8b61fb3cae76bc31561bafdb0a58ad12b;p=openwrt%2Fstaging%2Fblogic.git

[media] drivers/media/platform/mx2_emmaprp.c: adjust inconsistent IS_ERR and PTR_ERR

Change the call to IS_ERR to test the value that was just initialized and
is returned using PTR_ERR.

The semantic match that finds this problem is as follows:

(
if (IS_ERR(e)) { ... PTR_ERR(e) ... }

if (IS_ERR(e=e1)) { ... PTR_ERR(e) ... }
|
*if (IS_ERR(e))
 { ...
*  PTR_ERR(e1)
   ... }
)
// </smpl>
