From: Jian Shen <shenjian15@huawei.com> mainline inclusion from mainline-private-6.6 commit 5d7869e1587aebc4b6a9eec16da8b1c5e7a145ef category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICHMW9 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ---------------------------------------------------------------------- Currently the misc irq is initialized before reset_timer setup. But it will access the reset_timer in the irq handler. So initialize the reset_timer earlier.
