staging: most: compress return logic into one line 

Author: Eva Rachel Retuya <eraretuya@gmail.com>

Eliminate local variable 'ret' and modify return statement to contain
the value being returned directly instead of assigning it first to 'ret'
and returning this variable.

Coccinelle semantic patch used:
@@ expression e, ret; @@
-ret =
+return
	e;
-return ret;
