stable inclusion from stable-5.10.68 commit 87479b10eb72f82aa45e8dc6a3dd9bfaec38f9d7 bugzilla: 182671 https://gitee.com/openeuler/kernel/issues/I4EWUH
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit a946506c48f3bd09363c9d2b0a178e55733bcbb6 ]
The driver was registering IRQ 0 when no IRQ was set. This leads to warnings with newer kernels.
Clear the resource flags, so no resource is registered at all in this case.
