Subject: staging: rts5208: fix gcc-8 logic error warning
From: Arnd Bergmann <arnd@arndb.de>
commit 58930cced012adb01bc78b3687049b17ef44d0a3 upstream.
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.
