[patch v1 1/2] drivers/platform/x86: move module mlx-platform from arch/x86 to drivers/platform/x86

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vadim Pasternak <vadimp@xxxxxxxxxxxx>

Move module mlx-platform.c from arch/x86/platform/mellanox/ to
drivers/platform/x86/.
Remove folder arch/x86/platform/mellanox/ and update relevant Makefile
and Kconfig.
