Long PCI ID causing truncation

[sslupsky]

There are a few PCI vendor and device names when combined with the device codes (-nn option) causes a string length to exceed the size of the buffer and thus the output is truncated.

For instance,
Intel Corporation Xeon E7 v2/Xeon E5 v2/Core i7 Integrated Memory Controller 0 Channel Target Address Decoder Registers

generates the following string:
0000:ff:0f.2 System peripheral [0880]: Intel Corporation Xeon E7 v2/Xeon E5 v2/Core i7 Integrated Memory Controller 0 Channel Target Address Decoder Registers [808... (rev 04)

The problem can be fixed by increasing the size of the devbuf here:

pciutils/lspci.c

Line 293 in 10add64

char classbuf[128], devbuf[128];

I enlarged the buffers, but the correct solution is to trim enormous names in the ID database.
