Subject: [PATCH] driver: char: rpivid: Clean up error handling use of
|
|
ERR_PTR/IS_ERR
|
|
|
|
The driver used an unnecessary intermediate void* variable so it
|
|
only called ERR_PTR once to convert to the error value.
|
|
|
|
Switch to converting as the error arises to remove these intermediate
|
|
variables.
