Subject: [PATCH v2] i2c: i2c-elektor: Allow building on SMP kernels
Date: Sat, 22 Nov 2025 14:45:01 +0100	[thread overview]
Message-ID: <20251122141717.28570-1-linmag7@gmail.com> (raw)

In the past, the i2c-elektor driver was broken on SMP. Since then, there
appear to have been some fixes and cleanup work (as pointed out by Wolfram
Sang) to get rid of cli/sti usage and rely on spinlocks instead. Therefore,
let's allow building the driver on SMP kernels again.

I've tested this driver on an SMP kernel on an Alpha UP2000+ for a few days
without any problems.
