If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c4735a8b4e147d0cc66dee65602dd18244c67bec Author: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Date: Tue Nov 1 17:09:46 2022 +0200 fbdev: ssd1307fb: Drop optional dependency [ Upstream commit 025e3b507a3a8e1ee96a3112bb67495c77d6cdb6 ] Only a single out of three devices need a PWM, so from driver it's optional. Moreover it's a single driver in the entire kernel that currently selects PWM. Unfortunately this selection is a root cause of the circular dependencies when we want to enable optional PWM for some other drivers that select GPIOLIB.
