The patch titled drivers/media/video/gspca: introduce missing kfree has been removed from the -mm tree. Its filename was drivers-media-video-gspca-introduce-missing-kfree.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: drivers/media/video/gspca: introduce missing kfree From: Julia Lawall <julia@xxxxxxx> Error handling code following a kmalloc should free the allocated data.
