Subject: [RFT v2 03/48] MIPS, irq: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc
Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.
Note: this patch has been queued by Ralf Baechle <ralf@...ux-mips.org>.
Signed-off-by: Jiang Liu <jiang.liu@...ux.intel.com>
