2010-02-26V4L/DVB: firedtv: remove check for interrupting signalStefan Richter
FCP transactions as well as CMP transactions were serialized with mutex_lock_interruptible. It is extremely unlikly though that a signal will arrive while a concurrent process holds the mutex. And even if one does, the duration of a transaction is reasonably short (1.2 seconds if all retries time out, usually much shorter). Hence simplify the code to plain mutex_lock.

2010-02-26V4L/DVB: firedtv: do not DMA-map stack addressesStefan Richter
This is a portability fix and reduces stack usage. The DMA mapping API cannot map on-stack addresses, as explained in Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet payload buffers in firedtv (payload of write requests in avc_write and of lock requests in cmp_lock) to slab-allocated memory. We use the 512 bytes sized FCP frame buffer in struct firedtv for this purpose. Previously it held only incoming FCP responses, now it holds pending FCP requests and is then overwriten by an FCP response from the tuner subunit. Ditto for CMP lock requests and responses. Accesses to the payload buffer are serialized by fdtv->avc_mutex. As a welcome side effect, stack usage of the AV/C transaction functions is reduced by 512 bytes. Alas, avc_register_remote_control() is a special case: It previously did not wait for a response. To fit better in with the other FCP transactions, let it wait for an interim response.
