Subject: [PATCH] gpio: htc-egpio: Remove unused exported htc_egpio_get_wakeup_irq()
Git-commit: c34a024e4ee087b6d9e534160990082c3d9e7103
Patch-mainline: v5.4-rc1
References: jsc#SLE-12730
This function was never used upstream, and is a relic of the original
handhelds.org code the htc-egpio driver was based on.
