From 67566ae474e628c0077163d1e20d09d3e33b0ae3 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Sat, 8 Dec 2018 16:38:41 +0200 Subject: gpio: lpc18xx: fix GPIO controller driver build as a module The problem is reported for allmodconfig build setup: ERROR: "irq_chip_retrigger_hierarchy" [drivers/gpio/gpio-lpc18xx.ko] undefined! make[2]: *** [scripts/Makefile.modpost:92: __modpost] Error 1 make[1]: *** [Makefile:1271: modules] Error 2 My testing in runtime shows that it is sufficient to remove .irq_retrigger callback, which is assigned to unexported irq_chip_retrigger_hierarchy() function, I did't observe any regressions, and thus apparently it is a better fix rather than exporting the function defined in kernel/irq/chip.c (see commit 52b2a05fa7c8 ("genirq: Export IRQ functions for module use")) or sticking the GPIO controller driver build to built-in option only.
