| |
2.6.29-stable review patch. If anyone has any objections, please let us know.
------------------
From: Grant Likely <grant.likely@secretlab.ca>
commit d9f0c5f9bc74f16d0ea0f6c518b209e48783a796 upstream.
The MPC5200 PSC device is wired up to a dedicated interrupt line which is never shared. This patch removes the IRQF_SHARED flag from the request_irq() call which eliminates the "IRQF_DISABLED is not guaranteed on shared IRQs" warning message from the console output.
