4 Subject: [PATCH] staging: vchiq_arm: Unify the unload handling of
5 platform devs
6
7 A helper function vchiq_register_child was added to deal with
8 adding the platform devices. This returns NULL on failure, and
9 that is assigned to the struct platform_device. There is
10 therefore no way for remove to encounter an error pointer, so
11 checking for IS_ERR() is redundant.
