Madhuparna Bhowmik 82be3d65f4 drivers: char: tlclk.c: Avoid data race between init and interrupt handler ... [ Upstream commit 44b8fb6eaa ] After registering character device the file operation callbacks can be called. The open callback registers interrupt handler. Therefore interrupt handler can execute in parallel with rest of the init function. To avoid such data race initialize telclk_interrupt variable and struct alarm_events before registering character device. Found by Linux Driver Verification project (linuxtesting.org).
