Geert Uytterhoeven f40d484e16 reset: Fix crash when freeing non-existent optional resets ... [ Upstream commit 4a6756f56bcf8e64c87144a626ce53aea4899c0e ] When obtaining one or more optional resets, non-existent resets are stored as NULL pointers, and all related error and cleanup paths need to take this into account. Currently only reset_control_put() and reset_control_bulk_put() get this right. All of __reset_control_bulk_get(), of_reset_control_array_get(), and reset_control_array_put() lack the proper checking, causing NULL pointer dereferences on failure or release. Fix this by moving the existing check from reset_control_bulk_put() to __reset_control_put_internal(), so it applies to all callers. The double check in reset_control_put() doesn't hurt. Fixes: 17c82e206d ("reset: Add APIs to manage array of resets") Fixes: 48d71395896d54ee ("reset: Add reset_control_bulk API") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/2440edae7ca8534628cdbaf559ded288f2998178.1701276806.git.geert+renesas@glider.be Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Sasha Levin <sashal@kernel.org>		2024-01-08 11:29:43 +01:00
