-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.
