Merge tag 'i2c-for-6.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c fixes from Wolfram Sang:
 "I2C core fix replacing IS_ENABLED() with IS_REACHABLE()

  For host drivers, there are two fixes:

   - Tegra I2C Controller: Addresses a potential double-locking issue
     during probe. ACPI devices are not IRQ-safe when invoking runtime
     suspend and resume functions, so the irq_safe flag should not be
     set.

   - Qualcomm GENI I2C Controller: Fixes an oversight in the exit path
     of the runtime_resume() function, which was missed in the previous
     release"

  i2c: tegra: Do not mark ACPI devices as irq safe
  i2c: Use IS_REACHABLE() for substituting empty ACPI functions
  i2c: qcom-geni: Add missing geni_icc_disable in geni_i2c_runtime_resume
