From 8f48dbd6deaf5a14c924c1de08bf7e36526bf3e7 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Date: Sat, 18 Jun 2022 17:26:08 +0200 Subject: [PATCH] drm/bochs: Fix some error handling paths in bochs_pci_probe() The remove() function calls bochs_hw_fini() but this function is not called in the error handling of the probe. This call releases the resources allocated by bochs_hw_init() used in bochs_load(). Update the probe and bochs_load() to call bochs_hw_fini() if an error occurs after a successful bochs_hw_init() call.
