10 days	iio: accel: kxcjk-1013: reject duplicate event disable	Jiale Yao
	The IIO core does not filter duplicate writes to the event enable attribute. kxcjk1013_write_event_config() already ignores repeated enable requests, but a repeated disable request still calls kxcjk1013_set_power_state(data, false), dropping a runtime PM reference that was not acquired for this request. This can underflow the runtime PM usage count and trigger a "Runtime PM usage count underflow" warning. Return early when the requested state already matches ev_enable_state.

10 days	iio: proximity: isl29501: Fix return type of isl29501_register_writegrafted	Salah Triki
	isl29501_register_write() was returning a u32 instead of an int. Since the function returns negative error codes (such as -ERANGE or return values from i2c_smbus_write_byte_data()), returning an unsigned integer type prevents callers from correctly checking for negative error conditions. Fix this by changing the function return type from u32 to int. This was found through manual code review. Fixes: 1c28799257bc ("iio: light: isl29501: Add support for the ISL29501 ToF sensor.")
