-Subject: [PATCH 1/3] Kbuild: use -Wdeclaration-after-statement
-
-The kernel is moving from using `-std=gnu89` to `-std=gnu11`, permitting
-the use of additional C11 features such as for-loop initial declarations.
-
-One contentious aspect of C99 is that it permits mixed declarations and
-code, and for now at least, it seems preferable to enforce that
-declarations must come first.
-
-These warnings were already enabled in the kernel itself, but not
-for KBUILD_USERCFLAGS or the compat VDSO on arch/arm64, which uses
-a separate set of CFLAGS.
-
-This patch fixes an existing violation in modpost.c, which is not
-reported because of the missing flag in KBUILD_USERCFLAGS:
-
-| scripts/mod/modpost.c: In function ‘match’:
-| scripts/mod/modpost.c:837:3: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
-|   837 |   const char *endp = p + strlen(p) - 1;
-|       |   ^~~~~
