Subject: [PATCH 03/16] hwmon: ina3221: Fix type incompatibility with non-macro find_closest
Date: Thu, 15 May 2025 11:13:19 +0300	[thread overview]
Message-ID: <20250515081332.151250-4-asoponar@taladin.ro> (raw)
In-Reply-To: <20250515081332.151250-1-asoponar@taladin.ro>

The ina3221_conv_time array was previously declared as u16 but used with
find_closest(). With find_closest() now implemented as a function taking
signed int parameters instead of a macro, passing unsigned arrays causes
type incompatibility errors. This patch changes the array type from
u16 to int to ensure compatibility with the function signature and
prevent compilation errors.
