From e567c35f4909b6e752f63412ed6038c4d9aa9ede Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 3 Jan 2017 19:01:18 +0200 Subject: [PATCH] gpiolib: Update documentation of struct acpi_gpio_info It seems the code had been changed, but description left untouched. Update description of the struct acpi_gpio_info and relative comments accordingly.
