Subject: [PATCH v2 05/13] enc28j60: Switch to use module_spi_driver() macro

From: Andy Shevchenko <[email-masked]>
Date: Mon, 18 Mar 2019 18:10:54 +0200

Eliminate some boilerplate code by using module_spi_driver() instead of
->init() / ->exit(), moving the salient bits from ->init() into ->probe().
