      usb: renesas_usbhs: avoid uninitialized variable use · 672bfdaa
      Arnd Bergmann authored
      After the renesas_usbhs driver is enabled in ARM multi_v7_defconfig,
      we now get a new warning:
      
      renesas_usbhs/mod.c: In function 'usbhs_interrupt':
      renesas_usbhs/mod.c:246:7: warning: 'intenb1' may be used uninitialized in this function [-Wmaybe-uninitialized]
      
      gcc correctly points to a problem here, for the case that the
      device is in host mode, we use the intenb1 variable without
      having assigned it first. The state->intsts1 has a similar
      problem, but gcc cannot know that.
      
      This avoids the problem by initializing both sides of the
      comparison to zero when we don't read them from the respective
      registers.
