From bb79a0798d7c430f012f2f906fd7873f8976bc89 Mon Sep 17 00:00:00 2001 From: Oskar Schirmer Date: Thu, 23 Feb 2012 12:19:11 +0000 Subject: i2c: imx: fix imx driver to work though signal is pending Interrupt a test application for I2C based mc13xxx driven touch panel, SIGINT, causes open event file descriptor to be closed, which in turn causes I2C activity to mask PMIC local interrupts. This eventually ends up in i2c_imx_bus_busy to wait for some busy flag to toggle, but while waiting it would find a signal pending and break. The final symptom is the device is not closed down cleanly and thus not reopenable. Do without check for pending signal.
