Subject: [PATCH] i2c: also convert placeholder function to return errno
Date: Sat, 25 Jul 2020 16:07:36 +0200 [thread overview]
Message-ID: <20200725140736.3629-1-wsa+renesas@sang-engineering.com> (raw)
All i2c_new_device-alike functions return ERR_PTR these days, but this
fallback function was missed.
Fixes: 2dea645ffc21 ("i2c: acpi: Return error pointers from i2c_acpi_new_device()")
Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

I recall that -ENOSYS is returned in case something is not compiled in.
I am open for -ENODEV if this is deemed better...
