[PATCH 6.13 207/623] wifi: mt76: mt7915: fix register mapping

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

 



6.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Chiu <chui-hao.chiu@xxxxxxxxxxxx>

[ Upstream commit dd1649ef966bb87053c17385ea2cfd1758f5385b ]

Bypass the entry when ofs is equal to dev->reg.map[i].size.
Without this patch, it would get incorrect register mapping when the CR
address is located at the boundary of an entry.
