Subject: can: flexcan: flexcan_irq(): rename variable reg_iflag -> reg_iflag_rx
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4e26598a7d3cd1bf6a0843042997963f9828a6ba;p=openwrt%2Fstaging%2Fblogic.git

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.
