| |
Fixes gcc warning when building linux-next:
In file included from scripts/kconfig/zconf.tab.c:2537:0: scripts/kconfig/menu.c: In function ‘get_symbol_str’: scripts/kconfig/menu.c:590:18: warning: ‘jump’ may be used uninitialized in this function [-Wmaybe-uninitialized] jump->offset = strlen(r->s); ^ scripts/kconfig/menu.c:551:19: note: ‘jump’ was declared here struct jump_key *jump; ^ HOSTLD scripts/kconfig/conf
Moved the initialization of struct jump_key *jump outside the first 'if' branch so it can be available throughout the function.
Also uses the preferred pointer syntax for passing the size of a struct.
Tested on next-20141119.
