From 71564a26e3e9d29d3d8901eb32647c2c3a807e1f Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 23 Oct 2019 15:25:05 +0300 Subject: [PATCH] driver core: platform: Declare ret variable only once We may define ret variable only once and avoid adding it each time platform_get_irq_optional() get extended. For the sake of consistency do the same in __platform_get_irq_byname(). Signed-off-by: Andy Shevchenko Reviewed-by: Rafael J.
