From: Zhen Lei <thunder.leizhen@huawei.com> stable inclusion from stable-5.10.52 commit c381e695cfcddb4bb8c8f1e9fbaaedde5d1994b7 bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 7fea67710e9f6a111a2c9440576f2396ccd92d57 ] When call irq_get_irq_data() to get the IRQ's irq_data failed, an appropriate error code -ENOENT should be returned. However, we directly return 'err', which records the IRQ number instead of the error code.
