brcmfmac: pcie: fix oops on failure to resume and reprobe
stable inclusion from stable-5.10.65 commit 4663aaef24dffd004fa030b7434de7a7e9a34f26 bugzilla: 182361 https://gitee.com/openeuler/kernel/issues/I4EH3U Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=4663aaef24dffd004fa030b7434de7a7e9a34f26 -------------------------------- [ Upstream commit d745ca4f ] When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a hot resume and then fall back to removing the PCI device and then reprobing. If this probe fails, the kernel will oops, because brcmf_err, which is called to report the failure will dereference the stale bus pointer. Open code and use the default bus-less brcmf_err to avoid this.
