[PATCH 00/11] treewide: rename dev_info variables to something else

[PATCH 00/11] treewide: rename dev_info variables to something else

[Joe Perches]

There is a macro called dev_info that prints struct device specific
information.  Having variables with the same name can be confusing and
prevents conversion of the macro to a function.

Rename the existing dev_info variables to something else in preparation
to converting the dev_info macro to a function.
