From 60ef99656951513c012f59a5ad5eb2406da8f31c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 30 Dec 2020 16:45:40 +0100 Subject: [PATCH] FROMLIST: genirq: Export irq_check_status_bit Changing some inline functions to use the new irq_check_status_bit function out of line breaks calling them from loadable modules: ERROR: modpost: "irq_check_status_bit" [drivers/perf/arm_spe_pmu.ko] undefined! Export the function to make it work again. One can debate over whether this should be EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL(), as it could be called from any module before and making it GPL-only changes behavior. However all other symbols in this file are EXPORT_SYMBOL_GPL(), so I went with that for consistency.
