+Subject: [PATCH] can: flexcan: flexcan_irq(): rename variable reg_iflag ->
+ reg_iflag_rx
+
+This patch renames the variable reg_iflag in the flexcan_irq() function
+to reg_iflag_rx. This better reflects the contents of the varibale. It
+does not hold the unmodified iflag registers, instead all non RX
+interrupts have been masked.
