   - Make use of specific printk() format tags for various optimisations
   - Kconfig / module modifications / tweaking
   - Simplify obtaining resources (memory, device data) using unified
     API helpers
   - Bunch of Device Tree additions, conversions and adaptions
   - Convert a bunch of Regmap configurations to use the Maple Tree
     cache
   - Ensure correct includes are present and remove some that are not
     required
   - Remove superfluous code
   - Reduce amount of cycles spent in critical sections
   - Omit the use of redundant casts and if relevant replace with better
     ones
   - Swap out raw_spin_{un}lock_irq{save,restore}() for
     spin_{un}lock_irq{save,restore}()

  Bug Fixes:
   - Repair theoretical deadlock situation

mtd: key superblock by device number

2023-08-31T10:47:15+00:00

The mtd driver has similar problems than the one that was fixed in
commit dc3216b14160 ("super: ensure valid info").

The kill_mtd_super() helper calls shuts the superblock down but leaves
the superblock on fs_supers as the devices are still in use but puts the
mtd device and cleans out the superblock's s_mtd field.

This means another mounter can find the superblock on the list accessing
its s_mtd field while it is curently in the process of being freed or
already freed.

Prevent that from happening by keying superblock by dev_t just as we do
in the generic code.

mtd: spear_smi: Use helper function devm_clk_get_enabled()

2023-08-21T07:44:39+00:00

Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be
replaced by devm_clk_get_enabled() when driver enables (and possibly
prepares) the clocks for the whole lifetime of the device. Moreover, it is
no longer necessary to unprepare and disable the clocks explicitly, so drop
the label "err_irq".
