Revision f43e04ec46b67071d432fc3f368dc9891a3443e5 authored by Arnd Bergmann on 13 August 2012, 14:36:10 UTC, committed by Linus Torvalds on 14 August 2012, 04:50:36 UTC
Commit 7212157267 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.
