From: Linus Walleij Date: Thu, 18 Aug 2022 12:12:27 +0000 (+0200) Subject: regmap/hexagon: Properly fix the generic IO helpers X-Git-Tag: v6.6.17~6501^2~10 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f8f60615379c1b36d9220f3886fb9b229e95d8cd;p=platform%2Fkernel%2Flinux-rpi.git regmap/hexagon: Properly fix the generic IO helpers I was too naive in just including into hexagon: one has to specify defines for every call that uses a (static) inline or this will not work. Fix it up by providing proper defines for all shorthands that hexagon provides. Compile-tested with hexagon LLVM which is the only working cross compiler for hexagon ATM after commenting out the -fno-inline-functions-called-once switch which isn't working with LLVM.
