[PATCH 7.1 13/21] Input: rmi4 - fix bit count in bitmap_copy()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

7.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

commit f22dbbcbd1f70ed004a7bf8837e0f0c3cc230b78 upstream.

bitmap_copy() takes number of bits, not bytes (or longs). Correct
the bit count in rmi_driver_set_irq_bits() and
rmi_driver_clear_irq_bits().

Fixes: 2b6a321da9a2 ("Input: synaptics-rmi4 - add support for Synaptics RMI4 devices")
