Subject: [SERIAL] serial_cs: allow wildcarded quirks
X-Git-Tag: upstream/snapshot3+hdmi~37277^2~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a8244b564ccc46dabf2367008aecf2b380a9be8d;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

[SERIAL] serial_cs: allow wildcarded quirks

Some quirks we will introduce next apply to (eg) all cards of one
manufacturer.  Therefore, we need a way to list these in the quirk
table - use ~0 - this is not a possible device ID value.
