Subject: [PATCH] video: fbdev: sm501fb:  Fix deallocation of buffers order
Date: Tue,  6 Apr 2021 18:35:17 -0500	[thread overview]
Message-ID: <20210406233519.2205389-1-pakki001@umn.edu> (raw)

The resource release in sm501fb_remove() is not in the inverse order of
sm501fb_probe(), for the buffers. Release the info object after
deallocating the buffers.
