platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

2010-02-17pcmcia/yenta: add module parameter for O2 speedupsWolfram Sang2-16/+34
O2-bridges can do read prefetch and write burst. However, for some combinations of older bridges and cards, this causes problems, so it is disabled for those bridges. Now, as some users know their setup works with the speedups enabled, a new parameter is introduced to the driver. Now, a user can specifically enable or disable these features, while the default is what we have today: detect the bridge and decide accordingly. Fixes Bugzilla entry 15014.

The socket driver m8xx_pcmcia.c uses a static memory assignment, but io_offset is set to 0. Therefore, it seems proper to use the iodyn resource manager for this driver, as was previously the case (before commit 80128ff79d282cf71b1819dbca9b8dd47d8ed3e8).

2010-01-17pcmcia: improve check for same card in slot after resumeDominik Brodowski3-36/+46
During a suspend/resume cycle, an user may change the card in the PCMCIA/CardBus slot. The pcmcia_core can at least look at the socket state to check whether it is the same. For PCMCIA devices, move the detection and handling of such a change to ds.c. For CardBus devices, the PCI hotplug interface doesn't offer a "rescan" facility which also _removes_ devices no longer to be found behind a bridge. Therefore, remove and re-add all devices unconditionally.

2010-01-13tg3: Fix std rx prod ring handlingMatt Carlson1-2/+3
There are some tg3 devices that require the driver to post new rx buffers in smaller increments. Commit 4361935afe3abc3e5a93006b99197fac1fabbd50, "tg3: Consider rx_std_prod_idx a hw mailbox" changed how the driver tracks the rx producer ring updates, but it does not make any special considerations for the above-mentioned devices. For those devices, it is possible for the driver to hit the special case path, which updates the hardware mailbox register but skips updating the shadow software mailbox member. If the special case path represents the final mailbox update for this ISR iteration, the hardware and software mailbox values will be out of sync. Ultimately, this will cause the driver to use a stale mailbox value on the next iteration, which will appear to the hardware as a large rx buffer update. Bad things ensue. The fix is to update the software shadow mailbox member when the special case path is taken.
