Subject: dm: core: Check uclass_get() return value when dumping
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9dec2c1f03922977725d14ebc89fdc05b1f32511;p=u-boot.git

dm: core: Check uclass_get() return value when dumping

Update dm_dump_drivers() to use the return value from uclass_get() to
check the validity of uc. This is equivalent and should be more attractive
to Coverity.
