Subject: [PATCH] fixup! gpio-fsm: Avoid truncation of delay jiffies
|
||
|
|
|
||
|
|
The kernel's time unit of jiffies should be stored as an unsigned long
|
||
|
|
value. Storing it as an unsigned int, as gpio-fsm did, leads to
|
||
|
|
truncation and malfunction when the kernel is built for a 64-bit
|
||
|
|
platform.
