Subject: [PATCH] misc: xilinx_sdfec: add compat_ptr_ioctl()
Date:   Mon, 26 Oct 2020 21:28:01 +0530
Message-Id: <20201026155801.16053-1-harshalchau04@gmail.com>
Precedence: bulk

Driver has a trivial helper function to convert
the pointer argument and then call the native ioctl handler.
But now we have a generic implementation for that, so we can use it.
