Subject: [PATCH v2 07/20] Input: rmi4 - fix bit count in bitmap_copy()
Date: Mon,  4 May 2026 21:59:37 -0700	[thread overview]
Message-ID: <20260505045952.1570713-7-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20260505045952.1570713-1-dmitry.torokhov@gmail.com>

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")
Cc: stable@vger.kernel.org
Assisted-by: Gemini:gemini-3.1-pro
