[PATCH v2 0/4] wifi: mwifiex: drop asynchronous init waiting code

[Sascha Hauer]

This is a spin-off from my mwifiex cleanup series. I have split the
original single patch into a series which hopefully makes the changes
easier to follow and verify.

[PATCH v2 1/4] wifi: mwifiex: remove unnecessary queue empty check

[Sascha Hauer]

Since Commit 7bff9c974e1a ("mwifiex: send firmware initialization commands
synchronously") all initialization commands are sent synchronously which
means the command queue is empty when mwifiex_sta_init_cmd() returns. No
need to check for entries in the command code then, so remove the check.

Add a WARN_ON() just in case there is something wrong with the
reasoning.

[PATCH v2 2/4] wifi: mwifiex: let mwifiex_init_fw() return 0 for success

[Sascha Hauer]

mwifiex_sta_init_cmd() returns -EINPROGRESS as success indication when
the init param is true. Likewise mwifiex_init_fw() returns -EINPROGRESS
as success indication: It will either return -EINPROGRESS directly when
in mfg_mode or the return value of mwifiex_sta_init_cmd() when in normal
mode.

-EINPROGRESS is a leftover from times when the initialization commands
were sent asynchronously. Since Commit 7bff9c974e1a ("mwifiex: send
firmware initialization commands synchronously") the return value has
become meaningless, so change mwifiex_sta_init_cmd() and
mwifiex_init_fw() to return 0 for success.

[PATCH v2 3/4] wifi: mwifiex: drop asynchronous init waiting code

[Sascha Hauer]

Historically all commands sent to the mwifiex driver have been
asynchronous. The different commands sent during driver initialization
have been queued at once and only the final command has been waited
for being ready before finally starting the driver.

This has been changed in Commit 7bff9c974e1a ("mwifiex: send firmware
initialization commands synchronously"). With this the initialization
is finished once the last mwifiex_send_cmd_sync() (now
mwifiex_send_cmd()) has returned. This makes all the code used to
wait for the last initialization command to be finished unnecessary,
so it's removed in this patch.
