linux-toradex.git/arch/mips/include/asm/netlogic, branch v4.3-rc2 Linux kernel for Apalis and Colibri modules genirq: Remove irq argument from irq flow handlers 2015-09-16T13:47:51+00:00 Thomas Gleixner tglx@linutronix.de 2015-09-14T08:42:37+00:00 bd0b9ac405e1794d72533c3d487aa65b6b955a0c Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it.

Remove the argument.
