Subject: i2c: pca-platform: propagate error from i2c_pca_add_numbered_bus
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=78e6c5abeb4ad895867fc0ff7f61c858d4deb7c0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

i2c: pca-platform: propagate error from i2c_pca_add_numbered_bus

Rather than returning -ENODEV if i2c_pca_add_numbered_bus() fails,
propagate the error to aid debugging.
