   4 Subject: [PATCH] can: flexcan: flexcan_irq(): rename variable reg_iflag ->
   5  reg_iflag_rx
   6
   7 This patch renames the variable reg_iflag in the flexcan_irq() function
   8 to reg_iflag_rx. This better reflects the contents of the varibale. It
   9 does not hold the unmodified iflag registers, instead all non RX
  10 interrupts have been masked.
