usb: xhci: fix __le32/__le64 accessors in debugfs code
It looks like some of the xhci debug code is passing u32 to functions directly from __le32/__le64 fields. Fix this by using le{32,64}_to_cpu() on these to fix the following sparse warnings; xhci-debugfs.c:205:62: warning: incorrect type in argument 1 (different base types) xhci-debugfs.c:205:62: expected unsigned int [usertype] field0 xhci-debugfs.c:205:62: got restricted __le32 xhci-debugfs.c:206:62: warning: incorrect type in argument 2 (different base types) xhci-debugfs.c:206:62: expected unsigned int [usertype] field1 xhci-debugfs.c:206:62: got restricted __le32 ... [Trim down commit message, sparse warnings were similar -Mathias] Cc: <stable@vger.kernel.org> # 4.15+ Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/1572013829-14044-4-git-send-email-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
