[PATCH v2 14/38] fbdev/ep93xx-fb: Do not assign to struct fb_info.dev
From: Thomas Zimmermann
Date: Mon Jun 12 2023 - 10:15:03 EST
Do not assing the Linux device to struct fb_info.dev. The call to
register_framebuffer() initializes the field to the fbdev device.
Drivers should not override its value.
Fixes a bug where the driver incorrectly decreases the hardware
device's reference counter and leaks the fbdev device.
