Input: iqs7222 - trim force communication command
[ Upstream commit 10e629d31aacb2348a1e9110c31a29e98b31ce38 ]
According to the datasheets, writing only 0xFF is sufficient to
elicit a communication window. Remove the superfluous 0x00 from
the force communication command.
Fixes: e505edaedcb9 ("Input: add support for Azoteq IQS7222A/B/C")
