svcrpc: Revert "sunrpc/cache.h: replace simple_strtoul"
Commit bbf43dc888833ac0539e437dbaeb28bfd4fbab9f "sunrpc/cache.h: replace simple_strtoul" introduced new range-checking which could cause get_int to fail on unsigned integers too large to be represented as an int. We could parse them as unsigned instead--but it turns out svcgssd is actually passing down "-1" in some cases. Which is perhaps stupid, but there's nothing we can do about it now. So just revert back to the previous "sloppy" behavior that accepts either representation. Cc: stable@vger.kernel.org Reported-by: Sven Geggus <lists@fuchsschwanzdomain.de> Signed-off-by: J.
