The patch titled Subject: parport_pc: release IO region properly if unsupported ITE887x card is found has been removed from the -mm tree. Its filename was parport_pc-release-io-region-properly-if-unsupported-ite887x-card-is-found.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/ ------------------------------------------------------ From: Jiri Kosina <jkosina@xxxxxxx> Subject: parport_pc: release IO region properly if unsupported ITE887x card is found sio_ite_8872_probe() bails out if it detects no-parallel (1S, 2S) or unknown card. It doesn't call release_region() on the previously allocated resource though. This causes (a) leak of the resource (b) kernel oops when parport module is removed and /proc/ioports is read. This is because the string that has been associated to the IO port region is a static char array inside the already removed module. Let's call release_region() properly before baling out.
