Subject[PATCH 5.3 080/135] net: mscc: ocelot: fix __ocelot_rmw_ix prototype
Date
From: Vladimir Oltean <olteanv@gmail.com>

[ Upstream commit 17fdd7638cb687cd7f15a48545f25d738f0101e0 ]

The "read-modify-write register index" function is declared with a
confusing prototype: the "mask" and "reg" arguments are swapped.

Fortunately, this does not affect callers so far. Both arguments are
u32, and the wrapper macros (ocelot_rmw_ix etc) have the arguments in
the correct order (the one from ocelot_io.c).
