From 58930cced012adb01bc78b3687049b17ef44d0a3 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 5 Sep 2017 09:33:32 +0200 Subject: [PATCH] staging: rts5208: fix gcc-8 logic error warning As gcc-8 points out, the bit mask check makes no sense here: drivers/staging/rts5208/sd.c: In function 'ext_sd_send_cmd_get_rsp': drivers/staging/rts5208/sd.c:4130:25: error: bitwise comparison always evaluates to true [-Werror=tautological-compare] However, the code is even more bogus, as we have already checked for the SD_RSP_TYPE_R0 case earlier in the function and returned success. As seen in the mmc/sd driver core, SD_RSP_TYPE_R0 means "no response" anyway, so checking for a particular response would not help either. This just removes the nonsensical code to get rid of the warning.
