Subject: [PATCH] I2C: Fix sgi_xfer return value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a89923fff79f8eeed0ccdf51e13453754e48a71e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] I2C: Fix sgi_xfer return value

The sgi_xfer function returns 0 on success instead of the number of
transfered messages as it is supposed to. This patch fixes that.

Let's just hope that no client chip driver was relying on this
misbehavior.
