Subject: dm: Tidy up four minor code nits
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=f2bc6fc3316d85dcd36d88788c3c412213c7823c;p=u-boot.git

dm: Tidy up four minor code nits

There is a spelling mistake and two functions are missing comments
altogether. Also the flags declaration is correct, but doesn't follow
style. Finally, the uclass_get_device() function has some errors in
its documentation.

Fix these problems.
