The patch titled
8250.c: support specifying DW APB UARTs in device platform_data
has been removed from the -mm tree. Its filename was
8250c-support-specifying-dw-apb-uarts-in-device-platform_data.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: 8250.c: support specifying DW APB UARTs in device platform_data
From: "Will Newton" <[EMAIL PROTECTED]>
Allow the private_data field to be specified in platform_data for the
standard 8250/16550 UART. This field is used by DW APB type UARTs and
without this patch it's only possible to set this field when registering
the port by hand. If private_data is not set then the driver will
potentially oops with a NULL pointer dereference.
