[PATCH V1] mmc: sdhci-uhs2: remove unnecessary variables
Posted by Victor Shih 3 weeks, 4 days ago 
From: Victor Shih <victor.shih@genesyslogic.com.tw>

There are unnecessary variables in the sdhci_uhs2_send_command()
that will generate a warning when building the kernel.

Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202410252107.y9EgrTbA-lkp@intel.com/
