[PATCH 124/220] USB gadget: make Open Firmware device id constant

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Németh Márton <nm127@xxxxxxxxxxx>

The match_table field of the struct of_device_id is constant in <linux/of_platform.h>
so it is worth to make ace_of_match also constant.

The semantic match that finds this kind of pattern is as follows:

// <smpl>
