Subject: irqchip/bcm7038-l1: Consolidate chained IRQ handler install/remove
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a7946eed85a1031120d2c946d6e8e8520b32827;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

irqchip/bcm7038-l1: Consolidate chained IRQ handler install/remove

Chained irq handlers usually set up handler data as well. We now have
a function to set both under irq_desc->lock. Replace the two calls
with one.

Search and conversion was done with coccinelle:

expression E1, E2, E3;

-if (irq_set_handler_data(E1, E2) != 0)
-   BUG();

-irq_set_handler_data(E1, E2);

+irq_set_chained_handler_and_data(E1, E3, E2);
