Subject: [PATCH] fix(modules/battery): make rate positive if negative
|
||
|
|
|
||
|
|
on the Lenovo X13s, the battery firmware returns a negative value for
|
||
|
|
power_now, which is interpreted by the battery module as 0 because it
|
||
|
|
converts the string to unsigned long. This should be read as a long
|
||
|
|
instead, as the kernel specifies that power_now is an int:
