-Subject: i2c: imx: Fix reset of I2SR_IAL flag
-
-From: Christian Eggers <ceggers@arri.de>
-
-commit fa4d30556883f2eaab425b88ba9904865a4d00f3 upstream
-
-According to the "VFxxx Controller Reference Manual" (and the comment
-block starting at line 97), Vybrid requires writing a one for clearing
-an interrupt flag. Syncing the method for clearing I2SR_IIF in
-i2c_imx_isr().
