Re: [PATCH] Make nchg variable signed because the code compares this variable against negative values.

[Mauro Carvalho Chehab <mchehab@redhat.com>]

Jean-François,

This patch looks ok to me, although the description is not 100%. 

The sonixj driver compares the value for nchg with
		if (sd->nchg < -6 || sd->nchg >= 12) {

With u8, negative values won't work.

Please check.

Thanks!
Mauro
