Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and also it prints the error value.

Just in case if you want to save more LOCs, you may in some drivers
introduce temporary variable for device pointer, like

struct device *dev = &client->dev;
quoted hunk ↗ jump to hunk
