Subject: [PATCH] MIPS: fix duplicated slashes for Platform file path
Git-commit: cca2aac8acf470b01066f559acd7146fc4c32ae8
Patch-mainline: v5.16-rc1
References: stable-5.14.19

commit cca2aac8acf470b01066f559acd7146fc4c32ae8 upstream.

platform-y accumulates platform names with a slash appended.
The current $(patsubst ...) ends up with doubling slashes.

GNU Make still include Platform files, but in case of an error,
a clumsy file path is displayed:

  arch/mips/loongson2ef//Platform:36: *** only binutils >= 2.20.2 have needed option -mfix-loongson2f-nop.  Stop.
