Backport 5b6fadc from #69988.

Fixes: #68815

Taking a spinlock will result in interrupts being blocked in the MIPI
DBI driver, which is not desired behavior while issuing SPI transfers,
since the driver may use interrupts to drive the transfer

Fixes #68815

Feels a bit strange to approve this given I wrote it, but I think I need to since I'm the assignee

Right. As the maintainer, you approve that this is something that should be backported. Anyone could have flagged it for backporting, so we need maintainer approval.

When a maintainer submits patches for the subsystems, they maintain, to the main branch, their approval is implicit.
