[PATCH net-next] net: dsa: qca8k: Fix inconsistent use of jiffies vs milliseconds

From: Andrew Lunn
Date: Sun Dec 15 2024 - 12:44:20 EST


wait_for_complete_timeout() expects a timeout in jiffies. With the
driver, some call sites converted QCA8K_ETHERNET_TIMEOUT to jiffies,
others did not. Make the code consistent by changes the #define to
include a call to msecs_to_jiffies, and remove all other calls to
msecs_to_jiffies.
