[patch] mmc: mxs-mmc: remove unneeded NULL check

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Static checkers complain about the inconsistent NULL checking here:

	drivers/mmc/host/mxs-mmc.c:680 mxs_mmc_probe()
	warn: variable dereferenced before check 'ssp->dmach' (see line 660)

The variable can't actually be NULL so we can remove the check.
