[PATCH 07/12] Revert "PM / devfreq: Add show_one macro to delete the duplicate code"

Show all headers | View raw

This reverts commit 3104fa3081126c9bda35793af5f335d0ee0d5818.

The {min|max}_freq_show() show the stored value of the struct devfreq.
But, if the drivers/thermal/devfreq_cooling.c disables the specific
frequency value, {min|max}_freq_show() have to check this situation
before showing the stored value. So, this patch revert the macro
in order to add the additional codes.
