[PATCH 5.10.y-cip 03/39] mmc: renesas_sdhi: simplify reset routine a little


Lad Prabhakar
 

From: Wolfram Sang <wsa+renesas@...>

commit 9f809065d86dec2070263acedaa5758f8c9e95a9 upstream.

The 'reset' pointer is only populated for Gen2+. So, we don't need to
check for that flag inside the routine.
