| |
Fix the following build warning: drivers/misc/ioc4.c: In function ‘ioc4_probe’: drivers/misc/ioc4.c:194:16: warning: ‘start’ may be used uninitialized in this function [-Wmaybe-uninitialized] period = (end - start) / ^ drivers/misc/ioc4.c:148:11: note: ‘start’ was declared here uint64_t start, end, period; ^
As far as I can tell 'start' cannot really be used uninitialized here, but for the sanity of gcc output explicitly initialize it. Same goes for the 'end' variable.
Signed-off-by: Richard Leitner <dev@g0hl1n.net> --- Used gcc version was 4.9.1 (Debian 4.9.1-19) P.S.: I know I'm too late for 3.18 but hopefully it still helps. --- drivers/misc/ioc4.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
