Subject: [PATCH 5/7] habanalabs: fix type of variable
Date: Sun, 11 Jul 2021 15:54:16 +0300	[thread overview]
Message-ID: <20210711125418.17533-5-ogabbay@kernel.org> (raw)
In-Reply-To: <20210711125418.17533-1-ogabbay@kernel.org>

Recently, the size parameter in userptr structure was change to u64.
As a result, we need to change the type of the local range_size
in device_va_to_pa() to u64 to avoid overflow.
