treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

wifi: wl1251: fix memory leak in wl1251_tx_work

2025-04-02T10:57:50+00:00

The skb dequeued from tx_queue is lost when wl1251_ps_elp_wakeup fails
with a -ETIMEDOUT error. Fix that by queueing the skb back to tx_queue.

wifi: wlcore: fix unbalanced pm_runtime calls

2025-01-10T12:51:26+00:00

If firmware boot failes, runtime pm is put too often:
[12092.708099] wlcore: ERROR firmware boot failed despite 3 retries
[12092.708099] wl18xx_driver wl18xx.1.auto: Runtime PM usage count underflow!
Fix that by redirecting all error gotos before runtime_get so that runtime is
not put.

wifi: wlcore: sysfs: constify 'struct bin_attribute'

2024-12-18T18:05:06+00:00

The sysfs core now allows instances of 'struct bin_attribute' to be
moved into read-only memory. Make use of that to protect them against
accidental or malicious modifications.

wifi: wlcore: testmode: Constify strutc nla_policy

2024-12-09T15:58:43+00:00

'struct nla_policy' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:

wifi: Switch back to struct platform_driver::remove()

2024-11-11T12:10:45+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/net/wireless to use
.remove(), with the eventual goal to drop struct
platform_driver::remove_new(). As .remove() and .remove_new() have the
same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

En passant several whitespace changes are done to make indentation
consistent in the struct initializers.

wifi: mac80211: call rate_control_rate_update() for link STA

2024-10-23T14:43:27+00:00

In order to update the right link information, call the update
rate_control_rate_update() with the right link_sta, and then
pass that through to the driver's sta_rc_update() method. The
software rate control still doesn't support it, but that'll be
skipped by not having a rate control ref.

Since it now operates on a link sta, rename the driver method.

wifi: wl1251: Use IRQF_NO_AUTOEN flag in request_irq()

2024-09-18T13:54:30+00:00

As commit cbe16f35bee6 ("genirq: Add IRQF_NO_AUTOEN for request_irq/nmi()")
said, the code below is subobtimal. IRQF_NO_AUTOEN flag can be used by
drivers to request_irq(). It prevents the automatic enabling of the
requested interrupt in the same safe way. With that the usage can be
simplified and corrected.

	irq_set_status_flags(irq, IRQ_NOAUTOEN);
	request_irq(dev, irq...);
