Subject: [PATCH] staging: rtl8712: init_drv_sw(): Change return values
Git-commit: 690407fdc9dd8103a78c251c59513646f1bed50d
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430

Change return values of init_drv_sw from _SUCCESS and _FAIL to 0 and
-ENOMEM. Change return type from u8 to int to allow this.
Add a return variable to streamline return of error codes of called
functions.
Modify call site to check for non-zero return value instead of _FAIL.
