Subject: include: phy: fix NULL pointer check in phy_write()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7def4e621b7c65b4a3740a554dcbc807e23b1c19;p=u-boot.git

include: phy: fix NULL pointer check in phy_write()

phy_write() uses bus->write() instead of bus->read(). This means NULL
pointer pre-check needs to happen on bus->write instead of bus->read.
