Re: [PATCH] Staging:ks7010:ks_wlan_net.c: unneeded type casting removed

[Joe Perches]

A floating point constant cast to an int was giving
a false positive warning about unneeded cast to int.

e.g.:

	(fwrq->m >= (int)2.412e8) && (fwrq->m <= (int)2.487e8))

Fix it.

Though it's probably better to avoid float/double values
that are cast to int at all.
