Subject: watchdog: w83697hf_wdt: return ENODEV if no device was found
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0cb1c3e853e0d0f996f4e11863407bf31e6b7343;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

watchdog: w83697hf_wdt: return ENODEV if no device was found

Most WDT driver modules return ENODEV during modprobe if
no valid device was found, but w83697hf_wdt returns EIO.

Let w83697hf_wdt return ENODEV.
