Subject[PATCH 5.10 116/563] media: venus: core: Fix a resource leak in the error handling path of venus_probe()
Date
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 8cc7a1b2aca067397a016cdb971a5e6ad9b640c7 ]

A successful 'of_platform_populate()' call should be balanced by a
corresponding 'of_platform_depopulate()' call in the error handling path
of the probe, as already done in the remove function.

A successful 'venus_firmware_init()' call should be balanced by a
corresponding 'venus_firmware_deinit()' call in the error handling path
of the probe, as already done in the remove function.

Update the error handling path accordingly.

Fixes: f9799fcce4bb ("media: venus: firmware: register separate platform_device for firmware loader")
