From 69ffab9b9e698248cbb4042e47f82afb00dc1bb4 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Fri, 8 Dec 2023 08:38:57 -0800 Subject: [PATCH] irqchip/irq-xtensa-pic: Clean up - get rid of the cached_irq_mask variable - use BIT() macro instead of bit shifts - drop .disable and .enable as they are equivalent to the default implementations Signed-off-by: Max Filippov Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/r/20231208163857.82644-1-jcmvbkbc@gmail.com --- drivers/irqchip/irq-xtensa-pic.c | 31 ++++++++++++------------------- 1 file changed, 12 insertions(+), 19 deletions(-) diff --git a/drivers/irqchip/irq-xtensa-pic.c b/drivers/irqchip/irq-xtensa-pic.c index 0c18d1f1e264..f9d6fce4da33 100644 --- a/drivers/irqchip/irq-xtensa-pic.c +++ b/drivers/irqchip/irq-xtensa-pic.c @@ -12,6 +12,7 @@ * Kevin Chea */ +#include #include #include #include @@ -19,8 +20,6 @@ #include #include -unsigned int cached_irq_mask; - /* * Device Tree IRQ specifier translation function which works with one or * two cell bindings.
