H A D | omap-serial.c | 0324a821 Thu Sep 06 07:45:34 CDT 2012 Ruchika Kharwar <ruchika@ti.com> serial: omap: unlock the port lock
This patch unlocks the port lock before calling a serial_core API and re-acquires the port lock after calling it. This patch fixes a system freeze issue seen when the serial_core API uart_write_wakeup() eventually attempts to acquire the port lock already acquired by omap serial interrupt handler.
