From b3ee105c332efc49199e138822923be3562619aa Mon Sep 17 00:00:00 2001 From: Ajay Singh Date: Tue, 4 Sep 2018 12:09:40 +0530 Subject: [PATCH] staging: wilc1000: refactor code to move initilization in wilc_netdev_init() Refactor code to move the initialization of wilc related parameters in wilc_netdev_init() and move their deinitialization in wilc_netdev_cleanup(). For 'hif_workqueue' creation 'clients_count' check is not required as the single instance is maintained.
