From ec750f1082d7cc08ac6d0173e6e377d568c5b2b5 Mon Sep 17 00:00:00 2001 From: Xinming Hu Date: Wed, 14 Dec 2016 19:40:48 +0530 Subject: [PATCH] mwifiex: cleanup in PCIe flr code path adapter and card variables don't get freed during PCIe function level reset. "adapter->ext_scan" variable need not be re-initialized. fw_name and tx_buf_size initialization is moved to pcie specific code so that mwifiex_reinit_sw() can be used by SDIO.
