    Subject[PATCH 10/11] drivers/char/mem.c: Rename dev_info to bdi
    Date
    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.
