Subject: i2c-pxa: Fix adapter number
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=51e5709ad46127da9476f31336113b5401f94dba;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

i2c-pxa: Fix adapter number

It turns out that platform_device.id is a "u32" so testing it for being
nonnegative is useless when setting up an i2c adapte.  Instead,
do what the platform_bus code does and test it against the value "-1".
