2016-12-01ath9k: constify ath_bus_ops structureBhumika Goyal
Declare the structure ath_bus_ops as const as it is only passed as an argument to the function ath9k_init_device. This argument is of type const struct ath_bus_ops *, so ath_bus_ops structures with this property can be declared as const. Done using Coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct ath_bus_ops i@p = {...}; @ok1@ identifier r1.i; position p; expression e1,e2; @@ ath9k_init_device(e1,e2,&i@p) @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ static +const struct ath_bus_ops i={...}; @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct ath_bus_ops i; File size before: text data bss dec hex filename 1295 232 0 1527 5f7 ath/ath9k/ahb.o File size after: text data bss dec hex filename 1359 176 0 1535 5ff ath/ath9k/ahb.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2016-07-19ath9k: simplify the code-paths when not using the built-in EEPROMMartin Blumenstingl
There were two paths in the code for "external" eeprom sources. The code in eeprom.c only handled the cases where the eeprom data was loaded via request_firmware. ahb.c and pci.c on the other hand had some duplicate code which was only used when the eeprom data was passed via ath9k_platform_data. With this change all eeprom data handling is now unified in eeprom.c. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

It has been reported to cause problems, Jeremiah writes: On an Acer C720 laptop if a suspend is performed the screen freezes, the machine locks up, and according to the indicator lights it does not enter suspend.

2014-04-24ath9k: fix race in setting ATH_OP_INVALIDRajkumar Manoharan
The commit "ath9k: move sc_flags to ath_common" moved setting ATH_OP_INVALID flag below ieee80211_register_hw. This is causing the flag never being cleared randomly as the drv_start is called prior to setting flag. Fix this by setting the flag prior to register_hw.

2013-09-26wireless: ath9k: use dev_get_platdata()Jingoo Han

2013-05-27net: wireless: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound).

2011-04-12ath9k: Register id table for platform deviceVasanthakumar Thiagarajan
Currently the device id in the platform driver is hardcoded to an id which is specific to AR9130/AR9132 SOCs as it supports only wmac (wireless mac) of these SOCs. But this needs to be dynamic when we want to support different wmac of SOCs. So add id_table to driver to make it extendable to more SOCs.

2010-02-01ath9k: fix access to freed data on unloadPavel Roskin
Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access to common->bus_ops, which is already freed as part of the device data. Remove the cleanup field in struct ath_bus_ops, as it was never used properly. Remove ath_bus_cleanup(). Merge cleanup functions in place of the ath_bus_cleanup() calls.

2010-01-14ath9k: Fix panic on driver loadSujith

We've cleaned up ath_init_device() and its children enough to pass meaninful errors back from probe.
