stable inclusion from stable-5.10.50 commit 460bee90091ddeadc38837fbbd25e45b7cd695b2 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 31a9a318255960d32ae183e95d0999daf2418608 ]
A 'request_irq()' call is not balanced by a corresponding 'free_irq()' in the error handling path, as already done in the remove function.
Add it.
