Subject: mei: bus: set the device name before running fixup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=213dd193fab8288e2b0b96dc93f974ec33ba2298;p=linux-beck.git

mei: bus: set the device name before running fixup

The mei bus fixup use dev_xxx services for printing
to kernel log so we need to setup the device name
prior to running fixup hooks.
