 	struct platform_device *platform_device_alloc(
-			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.

+==================================
+
+ずっと知りたかった Linux 2.6 -stable リリースの全て
+
+"-stable" ツリーにどのような種類のパッチが受け入れられるか、どのような
+ものが受け入れられないか、についての規則-
+
+ - 明らかに正しく、テストされているものでなければならない。
+ - 文脈(変更行の前後)を含めて 100 行より大きくてはいけない。
+ - ただ一個のことだけを修正しているべき。
+ - 皆を悩ませている本物のバグを修正しなければならない。("これはバグで
+   あるかもしれないが..." のようなものではない)
+ - ビルドエラー(CONFIG_BROKENになっているものを除く), oops, ハング、デー
+   タ破壊、現実のセキュリティ問題、その他 "ああ、これはダメだね"という
+   ようなものを修正しなければならない。短く言えば、重大な問題。
+ - どのように競合状態が発生するかの説明も一緒に書かれていない限り、
+   "理論的には競合状態になる"ようなものは不可。
+ - いかなる些細な修正も含めることはできない。(スペルの修正、空白のクリー
+   ンアップなど)
+ - 対応するサブシステムメンテナが受け入れたものでなければならない。
+ - Documentation/SubmittingPatches の規則に従ったものでなければならない。
+
+-stable ツリーにパッチを送付する手続き-
+
+ - 上記の規則に従っているかを確認した後に、stable@kernel.org にパッチ
+   を送る。
+ - 送信者はパッチがキューに受け付けられた際には ACK を、却下された場合
+   には NAK を受け取る。この反応は開発者たちのスケジュールによって、数
+   日かかる場合がある。
+ - もし受け取られたら、パッチは他の開発者たちのレビューのために
+   -stable キューに追加される。
+ - セキュリティパッチはこのエイリアス (stable@kernel.org) に送られるべ
+   きではなく、代わりに security@kernel.org のアドレスに送られる。
+
+レビューサイクル-
+
+ - -stable メンテナがレビューサイクルを決めるとき、パッチはレビュー委
+   員会とパッチが影響する領域のメンテナ(提供者がその領域のメンテナで無
+   い限り)に送られ、linux-kernel メーリングリストにCCされる。
+ - レビュー委員会は 48時間の間に ACK か NAK を出す。
+ - もしパッチが委員会のメンバから却下れるか、メンテナ達やメンバが気付
+   かなかった問題が持ちあがり、linux-kernel メンバがパッチに異議を唱え
+   た場合には、パッチはキューから削除される。
+ - レビューサイクルの最後に、ACK を受けたパッチは最新の -stable リリー
+   スに追加され、その後に新しい -stable リリースが行われる。
+ - セキュリティパッチは、通常のレビューサイクルを通らず、セキュリティ
+   カーネルチームから直接 -stable ツリーに受け付けられる。
+   この手続きの詳細については kernel security チームに問い合わせること。
+
+レビュー委員会-
+
+ - この委員会は、このタスクについて活動する多くのボランティアと、少数の
+   非ボランティアのカーネル開発者達で構成されている。

- * 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.
