Most prefer separate patches for each type of change,
so this single patch could be 3 patches.

	do {
		if (foo)
			bar;
		else
			break;
	} while (baz);

is generally better written

	do {
		if (!foo)
			break;
		bar;
	} while (baz);

so

				if (!(tempword & 0x1f))
					break;

				ft100_copy_up_pkt(dev);
				cnt++;
			} while (cnt < MAX_RCV_LOOP);

or maybe

				if (!(tempword & 0x1f))
					break;

				ft100_copy_up_pkt(dev);
			} while (++cnt < MAX_RCV_LOOP);
