[PATCH 2/2] mmc: davinci_mmc: report all possible bus widths

From: Bastien Curutchet
Date: Thu Jul 11 2024 - 04:19:13 EST


A dev_info() at probe's end() report the supported bus width. It never
reports 8-bits width while the driver can handle it.

Update the info message at then end of the probe to report the use of
8-bits data when needed.
