treewide, timers: Rename from_timer() to timer_container_of()

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

2025-04-05T08:30:12Z

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. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

mmc: omap: Fix memory leak in mmc_omap_new_slot

2025-03-19T11:37:18Z

Add err_free_host label to properly pair mmc_alloc_host() with mmc_free_host() in GPIO error paths. The allocated host memory was leaked when GPIO lookups failed.

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

2024-10-14T10:29:01Z

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/mmc 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.

mmc: Convert from tasklet to BH workqueue

2024-07-08T09:41:30Z

The only generic interface to execute asynchronously in the BH context is tasklet; however, it's marked deprecated and has some design flaws. To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context. This patch converts drivers/mmc/* from tasklet to BH workqueue.

mmc: omap: restore original power up/down steps

2024-03-08T08:50:02Z

Commit e519f0bb64ef ("ARM/mmc: Convert old mmci-omap to GPIO descriptors") moved Nokia N810 MMC power up/down from the board file into the MMC driver. The change removed some delays, and ordering without a valid reason. Restore power up/down to match the original code. This matters only on N810 where the 2nd GPIO is in use. Other boards will see an additional delay but that should be a lesser concern than omitting delays altogether.

mmc: omap: fix broken slot switch lookup

2024-03-08T08:50:02Z

The lookup is done before host->dev is initialized. It will always just fail silently, and the MMC behaviour is totally unpredictable as the switch is left in an undefined state. Fix that.
