5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wenhua Lin <Wenhua.Lin@xxxxxxxxxx>
[ Upstream commit 26d9e5640d2130ee16df7b1fb6a908f460ab004c ]
The drivers uses a mutex and I2C bus access in its PMIC EIC chip
get implementation. This means these functions can sleep and the PMIC EIC
chip should set the can_sleep property to true.
This will ensure that a warning is printed when trying to get the
value from a context that potentially can't sleep.
Fixes: 348f3cde84ab ("gpio: Add Spreadtrum PMIC EIC driver support")
