[PATCH 1/2] mmc: block: Remove error check of hw_reset on reset

From: Christian Löhle
Date: Thu Oct 06 2022 - 09:39:00 EST


Before switching back to the right partition in mmc_blk_reset
there used to be a check if hw_reset was even supported.
This return value was removed, so there is no reason to check.

Fixes: fefdd3c91e0a ("mmc: core: Drop superfluous validations in mmc_hw|sw_reset()")
