Kuppuswamy Sathyanarayanan 6687aeb9cd platform/x86: intel_pmc_ipc: Use spin_lock to protect GCR updates ... Currently, update_no_reboot_bit() function implemented in this driver uses mutex_lock() to protect its register updates. But this function is called with in atomic context in iTCO_wdt_start() and iTCO_wdt_stop() functions in iTCO_wdt.c driver, which in turn causes "sleeping into atomic context" issue. This patch fixes this issue by replacing the mutex_lock() with spin_lock() to protect the GCR read/write/update APIs.
