Subject: arm64/efi: Make strrchr() available to the EFI namespace
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fdfb69a72522e97f9105a6d39a5be0a465951ed8;p=linux.git

arm64/efi: Make strrchr() available to the EFI namespace

libfdt gained a new dependency on strrchr, so make it available to the
EFI namespace before we update libfdt.

Thanks to Ard for providing this fix.
