Subject: platform/x86: msi-laptop: remove sparse_keymap_free() calls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7cb8aa8cafbe9ebc5ecd7ac6125264c958db48ad;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

platform/x86: msi-laptop: remove sparse_keymap_free() calls

As sparse_keymap_setup() now uses a managed memory allocation for the
keymap copy it creates, the latter is freed automatically.  Remove all
calls to sparse_keymap_free().

As this reduces msi_laptop_input_destroy() to one line, replace all
calls to that function with direct calls to input_unregister_device().
