Subject: IOMUX: Split out for_each_console_dev() helper macro
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=400797cad36850797307be3c56d2d5bc16aa02bb;p=u-boot.git

IOMUX: Split out for_each_console_dev() helper macro

It is not only less lines of code, but also better readability
when new macro is being in use. Introduce for_each_console_dev()
helper macro and convert current users to it.
