Subject: ACPI: battery: add sysfs serial number
X-Git-Tag: v2.6.25-rc1~297^2~3^2~2^2~1^2~10^3
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7c2670bbb53820d0a4fab8d74593eeccd1eef225;p=karo-tx-linux.git

ACPI: battery: add sysfs serial number

egrep serial /proc/acpi/battery/BAT0/info
serial number:           32090

serial number can tell you from the imminent danger
of beeing set on fire.
