Subject: [PATCH v2] iio:frequency:adf4377: Fix duplicated soft reset mask
Date: Tue, 30 Dec 2025 22:21:26 +0900	[thread overview]
Message-ID: <20251230132126.217802-1-suunj1331@gmail.com> (raw)
In-Reply-To: <20251230123609.210454-1-suunj1331@gmail.com>

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 incomplete reset status check.

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

Fixes: eda549e2e524 ("iio:frequency:adf4377: add support for ADF4377")
