[DIGImend-devel] [PATCH] hid: huion: Fix sparse warnings

[Nikolai K. <sp...@gm...>]

Fix sparse warnings in hid-huion.c by using correct buffer type for
retrieved string descriptor.

The warnings in question were:

    drivers/hid/hid-huion.c:144:44: sparse: cast to restricted __le16
    drivers/hid/hid-huion.c:145:44: sparse: cast to restricted __le16
    drivers/hid/hid-huion.c:146:51: sparse: cast to restricted __le16
    drivers/hid/hid-huion.c:147:30: sparse: cast to restricted __le16

Hi Jiri, Benjamin,

Thanks for the review. There is one minor problem, though. I didn't run a
sparse check and only just got a message with "sparse" warnings. This patch
fixes them.

If you wouldn't like adding a tiny patch like this, I can send another version
of the original patches. Otherwise, please feel free to just fixup my "Switch
to generating report descriptor" commit with this one.

I'll try to remember to run sparse next time before submitting the patches.

Thank you.

Nick
