Marian Buschsieweke e7c9451b55 drivers/pcf857x: use errno code for error reporting ... This makes it easier to use common error reporting such as `strerror()` or `tiny_strerror()` to give more insight on why something failed. The custom error codes via `enum` have been updated to be synonymous with the `errno` codes for backward compatibility. In addition, `pcf857x_init()` has been updated to no longer or together the return code, but rather abort on the first fail transaction and return the error code as is. Otherwise (when both fail due to different error codes) the returned error code may be garbage.		2023-11-22 10:29:33 +01:00
