In case of error, the function ion_device_create() returns ERR_PTR() and

Instead of storing the return value of a function call into a variable and
then returning it, we can club the two into a single return statement. This
change was made using the following semantic patch by Coccinelle:
add braces to if/else clause to fix the checkpatch issue braces {}
should be used on all arms of if/else block. Does not affect flow
