In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix GCC_GCC_PCIE_HOT_RST definition for WCN7850 GCC_GCC_PCIE_HOT_RST is wrongly defined for WCN7850, causing kernel crash on some specific platforms. Since this register is divergent for WCN7850 and QCN9274, move it to register table to allow different definitions. Then correct the register address for WCN7850 to fix this issue. Note IPQ5332 is not affected as it is not PCIe based device. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
