arm64: ras: Fix register_fhi_callback 2018-05-10T23:06:33+00:00 Rohit Khanna rokhanna@nvidia.com 2018-04-30T22:45:59+00:00 500aae6b29e76dfb658103d89e002e498f868472 The handler function can be invoked right after request_irq gets called. If FHI is triggered before CPU specific FHI handler is registered, there will be no one to clear the FHI. In order to prevent this problem this patch modifies the register_fhi_callback so that request_irq for FHI gets called only after CPU specific callback has been registered with the driver.
