[PATCH 00/10] staging: ks7010: some new cleanups

[Sergio Paracuellos]

This patch series continue with the driver cleanups. It just contains
trivial cleanups in some files of the driver. For this to be applied
properly previous sent patch series must be applied before.

    and rx queues

[PATCH 01/10] staging: ks7010: use linux circular buffer header macros to handle tx and rx queues

[Sergio Paracuellos]

This commit replace current custom implementation of some circular
buffer head and tail logic in favour of the use of macros defined
in linux circ_buf.h header. Queue related inline function names
have been review also.

[PATCH 02/10] staging: ks7010: change name and type for device_open_status field

[Sergio Paracuellos]

This commit changes type for device_open_status field of ks_wlan_private
structure from int to bool. This variable is only be set to 1
on ks_wlan_net_start and set to 0 on ks_wlan_net_stop. For this
purpose it is not necessary at all to use an integer because a bool
is enough. This also renames field name from device_open_status to
is_device_open.

[PATCH 03/10] staging: ks7010: avoid one level indentation in devio_rec_ind function

[Sergio Paracuellos]

This commit changes logic to handle with the status of the device
at first checking for close state to return directly instead
of just do the stuff when device is open. This improves readability
avoiding one level indentation.

[PATCH 05/10] staging: ks7010: change return value of ks_wlan_do_power_save function

[Sergio Paracuellos]

This commit change return value of ks_wlan_do_power_save function
from int to void. This function is just returning zero and return
value is not being checked also, so it is nonsense to return an
integer.

[PATCH 06/10] staging: ks7010: remove nonsense break from case block

[Sergio Paracuellos]

This commit removes 'break' from case block because the
code is just using the 'default' break for some cases and
this one can be included also there.

[PATCH 07/10] staging: ks7010: refactor code for hostif_sme_sleep_set function

[Sergio Paracuellos]

This commit refactors code for hostif_sme_sleep_set function. This
function was using a switch-case block to handle only two states
where the action to do for them is the same. Just refactor a bit
to check for return condition at first and doing the common action
after in other case.

I will. I think previous one to this series is not being applied at
all. Is it posible? The one with
cover-letter subject "cleanups continue" which contains 14 patches. It
has a mail thread with
Dan about circular buffer stuff to fix and no resend the series
because is the wrong one is the
last patch.

I have no idea, sorry, all of these patches are long-gone from my patch
queue.  If I haven't applied something, rebase and resend.  I'm dealing
with over a thousand staging driver patches right now, I can't stop and
"think" about what I already reviewed :)

thanks,
