Subject: staging: unisys: return meaningful error for visorchipset_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fbd91616036d565054a09a2a6ba0dd5ce3c69ad3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: unisys: return meaningful error for visorchipset_init()

The other error paths return meaningful error codes, except for the one
when registering a device, which just returned -1. Let's return ENODEV
when it fails to register instead.
