Subject: [PATCH 5.15 505/913] gpu: host1x: Fix a memory leak in host1x_remove()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 025c6643a81564f066d8381b9e2f4603e0f8438f ]

Add a missing 'host1x_channel_list_free()' call in the remove function,
as already done in the error handling path of the probe function.

Fixes: 8474b02531c4 ("gpu: host1x: Refactor channel allocation code")
