[PATCH v3 8/9] asm-generic: remove extra strn{cpy_from,len}_user declarations
From: Arnd Bergmann <arnd@kernel.org>
Date: 2021-07-22 12:51:22
Also in:
linux-arch, linux-mips, linux-s390, lkml
Subsystem:
qualcomm hexagon architecture, synopsys arc architecture, the rest, user-mode linux (uml) · Maintainers:
Brian Cain, Vineet Gupta, Linus Torvalds, Richard Weinberger, Anton Ivanov, Johannes Berg
From: Arnd Bergmann <arnd@arndb.de> As these are now in asm-generic, it's no longer necessary to declare them in the architecture.
