[PATCH 5.4 244/367] fbdev/ep93xx-fb: Do not assign to struct fb_info.dev

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


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


From: Thomas Zimmermann <tzimmermann@xxxxxxx>

commit f90a0e5265b60cdd3c77990e8105f79aa2fac994 upstream.

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.
