There's already a generic implementation so use that instead.
There is or there was? If there is now I am fine with this patch, but if
it already was there the author might have had a reason for adding a
local function and I would like to hear that reason.


atomic_orr() was introduced to this driver with

2014-03-06 5cbb9c285bdc brcmfmac: Use atomic functions for intstatus update.

as it seems atomic_set_mask() was not available cross arch. And atomic_or() in
generic code was indeed introduced after that

2014-04-23 560cb12a4080 locking,arch: Rewrite generic atomic support

Hence likely the reason author went with home grown atomic_orr()

Hi Vineet

Thanks for looking into the timeline. Will look into it and let you know.

Regards,
Arend
