When the battery is dry and BATTERY_FULL_DISCHARGED is set,
we should check BATTERY_DISCHARGING to decide the power status.
If BATTERY_DISCHARGING is set, the power status is not charging.
Or the power status should be charging.

This patch series add the use of display PWM driver and documentation
for Mediatek SoCs. The driver is used to support the backlight of
the panel. This is based on v4.1-rc1.

Hi,
I am using an ARM processor with CS8900 Ethernet card, it works fine in
kernel 2.6.11. But, recently I upgraded it to kernel 2.6.22, the
ipconfig.c started up a bond0 instead of eth0 with an IP address I
actually assigned to eth0 in cs89x0.c. The trouble was I cannot event
ping the ip add

Asynchronous communication mechanism is very effective mechanism among

Hello,
Apologize for off topic questions. While I am working on a device driver
in kernel 2.4.21, I need advices from kernel developers.
1. When the read() or write() is called from user applications, the
driver can either have a static buffer with limited size or dynamic
memory allocation (
