6.12-stable review patch. If anyone has any objections, please let me know.

From: Dmitry Nikiforov Dm1tryNk@yandex.ru
commit 024bf40edf1155e7a587f0ec46294049777d9b02 upstream.
If an error occurs during the initialization of `pdev_display`, the allocated platform device `pdev_capture` is not released properly, leading to a memory leak.
Adjust error path handling to fix the leak.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
