mmc: sdricoh_cs: Drop redundant in-parameter to sdricoh_query_status()
The in-parameter timeout is always set to TRANSFER_TIMEOUT by the callers of sdricoh_query_status(), hence let's drop it. Cc: Sascha Sommer <saschasommer@freenet.de> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Link: https://lore.kernel.org/r/20200414161413.3036-12-ulf.hansson@linaro.org
