[PATCH 5.15 020/691] Input: ads7846 - ratelimit the spi_sync error message

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

 



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

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

From: Marek Vasut <marex@xxxxxxx>

[ Upstream commit ccbfea78adf75d3d9e87aa739dab83254f5333fa ]

In case the touch controller is not connected, this message keeps scrolling
on the console indefinitelly. Ratelimit it to avoid filling kernel logs.

"
ads7846 spi2.1: spi_sync --> -22
