Subject: [PATCH RESEND] firmware: raspberrypi: Fix type assignment
Date: Mon, 2 Jan 2023 12:52:55 +0100 [thread overview]
Message-ID: <20230102115255.17802-1-maxime@cerno.tech> (raw)
We silently cast an unsigned int into a __le32 which makes sparse
complain. Moreover, we never actually convert endianness between the
CPU's and the expected little-endian value. Fix both at once by calling
cpu_to_le32().
Fixes: 40c31955e4e9 ("firmware: raspberrypi: Provide a helper to query a clock max rate")
Reported-by: kernel test robot <lkp@intel.com>
