Subject: [PATCH v5 07/14] iio: magnetometer: yas530: Move printk %*ph parameters out from stack
Date: Mon,  8 Aug 2022 01:06:46 +0200	[thread overview]
Message-ID: <0f80659d4a5865a267cf75eaf14a23b8319ddb92.1659909060.git.jahau@rocketmail.com> (raw)
In-Reply-To: <cover.1659909060.git.jahau@rocketmail.com>

Use less stack by modifying %*ph parameters.

Additionally, in the function yas530_get_calibration_data(), the debug dump was
extended to 16 elements as this is the size of the calibration data array of
YAS530.
