Subject: [PATCH] eventtable.h: use correct array sizes to fix building against
 4.7+ headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

During the 4.7 development cycle, commit 9a9b6aa6a8 (Input: add
SW_PEN_INSERTED define) got added, which has the same numerical value as
SW_MAX:

+#define SW_PEN_INSERTED                0x0f  /* set = pen inserted */
+#define SW_MAX                 0x0f

This breaks the build as the SW_NAME array is sized using the SW_MAX macro:

In file included from eventtable.h:21:0,
                 from eventnames.c:11:
evtable_SW.inc:17:1: error: array index in initializer exceeds array bounds
 EV_MAP(SW_PEN_INSERTED),
 ^
evtable_SW.inc:17:1: error: (near initialization for ‘SW_NAME’)

The arrays should be sized using the <foo>_CNT (which is MAX+1) macros
instead of <foo>_MAX.  These got added during the 2.6.24 development cycle,
so it should be safe to do so unconditially:

commit 7b19ada2ed3c1eccb9fe94d74b05e1428224663d

    get rid of input BIT* duplicate defines
