[media] m88ds3103: fix undefined division
s32tmp in the below code may be negative, and dev->mclk_khz is an unsigned type. s32tmp = 0x10000 * (tuner_frequency - c->frequency); s32tmp = DIV_ROUND_CLOSEST(s32tmp, dev->mclk_khz); This is undefined, as DIV_ROUND_CLOSEST is undefined for negative dividends when the divisor is of unsigned type. So, change mclk_khz to be signed (s32). Signed-off-by: Peter Rosin <peda@axentia.se> Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
