Subject: [PATCH] staging: rtl8712: r8712_append_mpdu_unit(): Change return type
Git-commit: bc6132f141b75ea1ee67574bf44adfd0433cad17
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430

Change return type of r8712_append_mpdu_unit from u8 to void and remove
its return statement as it always returns only _SUCCESS. Modify call
sites to simply call this function instead of checking its return value,
and execute all the statements in the if-block for when the function
returns _SUCCESS.
