6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Markus Schneider-Pargmann <msp@xxxxxxxxxxxx>
[ Upstream commit a572fea86c9b06cd3e6e89d79d565b52cb7e7cff ]
active_interrupts is a cache for the enabled interrupts and not the
global masking of interrupts. Do not clear this variable otherwise we
may loose the state of the interrupts.
Fixes: 07f25091ca02 ("can: m_can: Implement receive coalescing")
