From: Horst Schirmeier Date: Thu, 28 Jul 2005 13:32:20 +0000 (+0200) Subject: [PATCH] USB: pl2303_update_line_status data length fix X-Git-Tag: v2.6.16-rc1~474^2~22^2~10^2~31 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=95f209f93663103db2a8fb989e226ac68a98b036;p=linux-2.6-omap-h63xx.git [PATCH] USB: pl2303_update_line_status data length fix Minimum data length must be UART_STATE + 1, as data[UART_STATE] is being accessed for the new line_state. Although PL-2303 hardware is not expected to send data with exactly UART_STATE length, this keeps it on the safe side.
