kconfig: display recursive dependency resolution hint just once
Commit 1c199f2878f6 ("kbuild: document recursive dependency limitation / resolution") probably intended to show a hint along with "recursive dependency detected!" error, but it missed to add {...} guard, and the hint is displayed in every loop of the dep_stack traverse, annoyingly. This error was detected by GCC's -Wmisleading-indentation when switching to build-time generation of lexer/parser. scripts/kconfig/symbol.c: In function ‘sym_check_print_recursive’: scripts/kconfig/symbol.c:1150:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation] if (stack->sym == last_sym) ^~ scripts/kconfig/symbol.c:1153:4: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’ fprintf(stderr, "For a resolution refer to Documentation/kbuild/kconfig-language.txt\n"); ^~~~~~~ I could simply add {...} to surround the three fprintf(), but I rather chose to move the hint after the loop to make the whole message readable.
