- char *name, unsigned id);
+ const char *name, int id);
You can use platform_device_alloc() to dynamically allocate a device, which
you will then initialize with resources and platform_device_register().
A better solution is usually:
struct platform_device *platform_device_register_simple(
- char *name, unsigned id,
- struct resource *res, unsigned nres);
+ const char *name, int id,
+ struct resource *res, unsigned int nres);
You can use platform_device_register_simple() as a one-step call to allocate
and register a device.

- * CHANGELOG
- * Version 2.1d
- * 11-November-2007 Jiri Slaby, Frank Seidel
- * - Big rework of multicard support by Jiri
- * - Major cleanups (semaphore to mutex, endianess, no major reservation)
- * - Optimizations
- *
- * Version 2.1c
- * 30-October-2007 Frank Seidel
- * - Completed multicard support
- * - Minor cleanups
- *
- * Version 2.1b
- * 07-August-2007 Frank Seidel
- * - Minor cleanups
- * - theoretical multicard support
- *
- * Version 2.1
- * 03-July-2006 Paul Hardwick
- *
- * - Stability Improvements. Incorporated spinlock wraps patch.
- * - Updated for newer 2.6.14+ kernels (tty_buffer_request_room)
- * - using __devexit macro for tty
- *
- *
- * Version 2.0
- * 08-feb-2006 15:34:10:Ulf
- *
- * -Fixed issue when not waking up line disipine layer, could probably result
- * in better uplink performance for 2.4.
- *
- * -Fixed issue with big endian during initalization, now proper toggle flags
- * are handled between preloader and maincode.
- *
- * -Fixed flow control issue.
- *
- * -Added support for setting DTR.
- *
- * -For 2.4 kernels, removing temporary buffer that's not needed.
- *
- * -Reading CTS only for modem port (only port that supports it).
- *
- * -Return 0 in write_room instead of netative value, it's not handled in
- * upper layer.
- *
- * --------------------------------------------------------------------------
- * Version 1.0
- *
- * First version of driver, only tested with card of type F32_2.
- * Works fine with 2.4 and 2.6 kernels.
- * Driver also support big endian architecture.

IIId. Synchronization
Most operations are synchronized on the np->lock irq spinlock, except the
-performance critical codepaths:
-
-The rx process only runs in the interrupt handler. Access from outside
-the interrupt handler is only permitted after disable_irq().
-
-The rx process usually runs under the netif_tx_lock. If np->intr_tx_reap
-is set, then access is permitted under spin_lock_irq(&np->lock).
-
-Thus configuration functions that want to access everything must call
- disable_irq(dev->irq);
- netif_tx_lock_bh(dev);
- spin_lock_irq(&np->lock);
-
-IV. Notes
-
-NatSemi PCI network controllers are very uncommon.
+recieve and transmit paths which are synchronised using a combination of
+hardware descriptor ownership, disabling interrupts and NAPI poll scheduling.
