Subject: [PATCH] habanalabs: correctly cast variable to __le32
Date: Tue,  3 Sep 2019 12:03:06 +0300	[thread overview]
Message-ID: <20190903090306.11724-1-oded.gabbay@gmail.com> (raw)

When using the macro le32_to_cpu(x), we need to correctly convert x to be
__le32 in case it is defined as u32 variable.
