[PATCH 2/6] ath10k: make wmi_service_name() warn about missing service ids

[Kalle Valo]

When adding a new value to enum wmi_service it's very easy to miss that the new
value should be also added to wmi_service_name() mapping function. Modify the
function so that GCC can now warn about this:

drivers/net/wireless/ath/ath10k/wmi.h:385:2: warning: enumeration value 'WMI_SERVICE_FOO' not handled in switch [-Wswitch]

And also add a reminder to the enum.

Thanks to Jouni Malinen for the idea.

[PATCH 3/6] ath10k: change wmi.h to include only ieee80211.h

[Kalle Valo]

wmi.h does not use anything from mac80211.h so change it to include only
ieee80211.h.

[PATCH 4/6] ath10k: align ath10k_htt_txbuf structures

[Kalle Valo]

With W=1 GCC warns:

drivers/net/wireless/ath/ath10k/htt.h:1746:1: warning: alignment 1 of 'struct ath10k_htt_txbuf_32' is less than 4 [-Wpacked-not-aligned]
drivers/net/wireless/ath/ath10k/htt.h:1753:1: warning: alignment 1 of 'struct ath10k_htt_txbuf_64' is less than 4 [-Wpacked-not-aligned]

Fix that by using __align(4). Compile tested only.

[PATCH 5/6] ath10k: fix documentation in ath10k_wow_convert_8023_to_80211()

[Kalle Valo]

With W=1 there's a warning:

drivers/net/wireless/ath/ath10k/wow.c:93: warning: Function parameter or member 'new' not described in 'ath10k_wow_convert_8023_to_80211'
drivers/net/wireless/ath/ath10k/wow.c:93: warning: Function parameter or member 'old' not described in 'ath10k_wow_convert_8023_to_80211'

Fix it by changing the documentation marker '/**' to a normal code comment.
While at it, clean up the line wrapping.

[PATCH 6/6] ath10k: copy the whole struct ath10k_bus_params in ath10k_core_register()

[Kalle Valo]

Instead of copying fields one by one copy the whole structure. This way there's
no need to modify the function every time we add a new field to the struct.

Compile tested only.
