Yes, this could use bool, but would probably be better
written without continual at all

as it is before this patch:

static u16 efuse_get_current_size(struct ieee80211_hw *hw)
{
	int continual = true;
	u16 efuse_addr = 0;
	u8 hworden;
	u8 efuse_data, word_cnts;

	while (continual && efuse_one_byte_read(hw, efuse_addr, &efuse_data)
	       && (efuse_addr < EFUSE_MAX_SIZE)) {
		if (efuse_data != 0xFF) {
			hworden = efuse_data & 0x0F;
			word_cnts = efuse_calculate_word_cnts(hworden);
			efuse_addr = efuse_addr + (word_cnts * 2) + 1;
		} else {
			continual = false;
		}
	}

	return efuse_addr;
}

I think writing it without continual, which is effectively
an ersatz "break", would be better

Something like:

static u16 efuse_get_current_size(struct ieee80211_hw *hw)
{
	u16 efuse_addr = 0;
	u8 hworden;
	u8 efuse_data, word_cnts;

	while (efuse_one_byte_read(hw, efuse_addr, &efuse_data) &&
	       (efuse_addr < EFUSE_MAX_SIZE) {
		if (efuse_data == 0xff)
			break;
		hworden = efuse_data & 0x0F;
		word_cnts = efuse_calculate_word_cnts(hworden);
		efuse_addr = efuse_addr + (word_cnts * 2) + 1;
	}

	return efuse_addr;
}
