From: Michał Kępień Date: Fri, 19 May 2017 07:44:46 +0000 (+0200) Subject: platform/x86: fujitsu-laptop: explicitly pass ACPI device to call_fext_func() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=84631e0c8b90411b424682eec4084006fae3f2cc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git platform/x86: fujitsu-laptop: explicitly pass ACPI device to call_fext_func() Prepare for not using module-wide data in call_fext_func() by explicitly passing it a pointer to struct acpi_device while still using a module-wide pointer in each call. Doing this enables call_fext_func() to fetch the ACPI handle from its argument, making the acpi_handle field of struct fujitsu_laptop useless, so remove that field. While we are at it, the dev field of the same structure is assigned in acpi_fujitsu_laptop_add() but not used for anything, so remove it as well.
