Re: linux-next: build warning after merge of the phy-next tree

Hi Kishon,
After merging the phy-next tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/phy/phy-rockchip-inno-usb2.c: In function 'rockchip_chg_detect_work':
drivers/phy/phy-rockchip-inno-usb2.c:717:7: warning: 'tmout' may be used 
uninitialized in this function [-Wmaybe-uninitialized]
     if (tmout) {
        ^

Introduced by commit

   0c42fe48fd23 ("phy: rockchip-inno-usb2: support otg-port for rk3399")
The variable "tmout" is initialized in the prior  code "case 
USB_CHG_STATE_WAIT_FOR_DCD",
and this case will be executed before "if (tmout)", so I think it's a 
mis-warning for some
special compiler.

Could you provide me some suggestion about this warning? Should I upload 
a new patch to
fix this compiler mis-warning or just ignore it ？ :-)

Best regards，
         wulf
