Subject: [PATCH] i2c: i2c-elektor: Allow building on SMP kernels
Date: Sat, 22 Nov 2025 13:26:13 +0100 [thread overview]
Message-ID: <20251122122846.28493-1-linmag7@gmail.com> (raw)
It the past the i2c-elektor driver has been broken on SMP, as it seems
there has since been some fixes/cleanup work to get rid of cli/sti and
rely on spinlocks instead (as pointed out by Wolfram Sang). Tested this
driver on SMP kernel on Alpha/UP2000+ for a few days without any problems.

This supports the PCF8584 ISA bus I2C adapter. Say Y if you own
