[PATCH v2] iio:frequency:adf4377: Fix duplicated soft reset mask
Posted by SeungJu Cheon 2 weeks ago
The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK
twice instead of checking both SOFT_RESET_MSK (bit 0) and
SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check.

Fix by using both masks as done in regmap_update_bits() above.

Yes, but this commit message completely ignored discussion
https://lore.kernel.org/linux-iio/20251230123609.210454-1-suunj1331@gmail.com/
So it should have summarised the question and answer.

Also this one mistakenly marked v2.
