Subject: [PATCH AUTOSEL 5.7 144/388] staging: wfx: fix overflow in frame counters
From: Jérôme Pouiller <jerome.pouiller@...abs.com>
[ Upstream commit 87066173e34b0ca5d041d5519e6bb030b1958184 ]
It has been reported that trying to send small packets of data could
produce a "inconsistent notification" warning.
It seems that in some circumstances, the number of frame queued in the
driver could greatly increase and exceed UCHAR_MAX. So the field
"buffered" from struct sta_priv can overflow.
Just increase the size of "bueffered" to fix the problem.
Fixes: 7d2d2bfdeb82 ("staging: wfx: relocate "buffered" information to sta_priv")
