Tsuchiya Yuto b38258b693 mwifiex: fix mwifiex_shutdown_sw() causing sw reset failure ... [ Upstream commit fa74cb1dc0f4da46c441b735ca865ac52de42c0e ] When a PCIe function level reset (FLR) is performed but without fw reset for some reasons (e.g., on Microsoft Surface devices, fw reset requires other quirks), it fails to reset wifi properly. You can trigger the issue on such devices via debugfs entry for reset: $ echo 1 | sudo tee /sys/kernel/debug/mwifiex/mlan0/reset and the resulting dmesg log: [ 45.740508] mwifiex_pcie 0000:03:00.0: Resetting per request [ 45.742937] mwifiex_pcie 0000:03:00.0: info: successfully disconnected from [BSSID]: reason code 3 [ 45.744666] mwifiex_pcie 0000:03:00.0: info: shutdown mwifiex...

This commit fixes mwifiex_shutdown_sw() by adding the missing mwifiex_init_shutdown_fw().
