regmap-irq: Provide IRQ resource request and release callbacks

2026-07-03T15:28:16+00:00

The users which rely on regmap IRQ to create the IRQ chip may also want to have an additional tracking of the IRQ requests and releases. Provide a callback for them.

regmap: maple: Workaround for another false-positive compiler warning

2026-06-29T18:15:50+00:00

Similar to the issue fixed in commit 542440fd7b30 ("regmap: maple: work around gcc-14.1 false-positive warning"), I see an uninitialized warning for upper_index and upper_last. Happens with arc-linux-gnu-gcc (Debian 15.3.0-1) 15.3.0 on an allmodconfig for ARCH=arc.

regcache: Make ->exit() callback return void

2026-06-29T13:16:58+00:00

We do not check an error code from ->exit() callback, nor we ever return one (it's always 0, meaning success). Make ->exit() callback return void. Signed-off-by: Andy Shevchenko Link: https://patch.msgid.link/20260618194036.3275202-1-andriy.shevchenko@linux.intel.com Signed-off-by: Mark Brown

regcache: Do not overwrite error code when finalizing cache after error

2026-06-16T13:13:48+00:00

During regcache initialization, if an error occurs in the cache_ops->populate callback, and if cache operations include an exit callback, the error code from populate() is overwritten with the return value from exit(). This hides the error condition from the caller of regcache_init(), and can cause NULL pointer dereferences when the regcache is later accessed.

regmap: reject volatile update_bits() in cache-only mode

2026-05-28T14:15:46+00:00

Prevent _regmap_update_bits() from accessing hardware when the register map is in cache-only mode. Unlike regmap_raw_read() and _regmap_read(), the volatile _regmap_update_bits() fast path bypasses the cache_only check. This can result in unexpected hardware accesses while the device is suspended. Return -EBUSY to ensure behavior is consistent with other cache-only access paths.

regmap-i2c: fix sparse warning in regmap_smbus_word_write_reg16

2026-05-21T08:47:39+00:00

i2c_smbus_write_word_data() expects a plain u16, but cpu_to_le16() returns __le16 (a sparse-restricted endian type), causing: drivers/base/regmap/regmap-i2c.c:340: sparse: incorrect type in argument 3 (different base types) expected unsigned short [usertype] value got restricted __le16 [usertype] SMBus already defines byte ordering internally, so cpu_to_le16() is wrong here. Replace it with a plain (u16) cast.
