From: Yash Shah Date: Tue, 28 Jan 2020 05:24:21 +0000 (+0530) Subject: gpio: sifive: fix static checker warning X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a924eae75106258c0797706a0578c5af499c9ff5;p=linux.git gpio: sifive: fix static checker warning Typcasting "irq_state" leads to the below static checker warning: The fix is to declare "irq_state" as unsigned long instead of u32. drivers/gpio/gpio-sifive.c:97 sifive_gpio_irq_enable() warn: passing casted pointer '&chip->irq_state' to 'assign_bit()' 32 vs 64.
