我們有個老產(chǎn)品需要CH9344 在linux3.0.35下的驅(qū)動，論壇上最新的1.8版本驅(qū)動需要內(nèi)核版本在3.4以上。能否將老版本驅(qū)動發(fā)我一份，謝謝！郵箱:個人信息保護，已隱藏

您好，郵件已發(fā)送，請注意查收。

已收到，但是編譯有問題：

1.

error:?implicit?declaration?of?function?'tty_port_tty_hangup'

這個函數(shù)我全局搜索了，除了ch9344.c中有引用，內(nèi)核其他地方未見引用和定義。

2.

error:?incompatible?types?when?assigning?to?type?'struct?ktermios?*'?from?type?'struct?ktermios'

等號兩邊類型不匹配

您好，重新發(fā)了驅(qū)動，麻煩重新編譯試下。

你好，編譯后有一處warning:

?CC??????drivers/usb/serial/ch9344.o
drivers/usb/serial/ch9344.c:?In?function?'ch9344_tty_set_termios':
drivers/usb/serial/ch9344.c:1532:29:?warning:?initialization?from?incompatible?pointer?type?[enabled?by?default]

相關(guān)代碼：

static?void?ch9344_tty_set_termios(struct?tty_struct?*tty,
????????????????struct?ktermios?*termios_old)
{
????????struct?ch9344?*ch9344?=?tty->driver_data;
????????struct?ktermios?*termios?=?&tty->termios;????//?tty->termios為struct?ktermios?*類型
????????
????????。。。
?}

修改為：

static?void?ch9344_tty_set_termios(struct?tty_struct?*tty,
????????????????struct?ktermios?*termios_old)
{
????????struct?ch9344?*ch9344?=?tty->driver_data;
????????struct?ktermios?*termios?=?tty->termios;
????????
????????。。。
?}

已編譯通過，目前在做測試
