Subject: [PATCH] platform/x86: hp_accel: Fix an error handling path in 'lis3lv02d_probe()'
Date:   Sun,  7 Nov 2021 20:57:07 +0100
Message-Id: <5a4f218f8f16d2e3a7906b7ca3654ffa946895f8.1636314074.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

If 'led_classdev_register()' fails, some additional resources should be
released.

Add the missing 'i8042_remove_filter()' and 'lis3lv02d_remove_fs()' calls
that are already in the remove function but are missing here.

Fixes: a4c724d0723b ("platform: hp_accel: add a i8042 filter to remove HPQ6000 data from kb bus stream")
Fixes: 9e0c79782143 ("lis3lv02d: merge with leds hp disk")
