Subject: [PATCH] usb: host: ehci-platform: BUG_ON() to WARN_ON() on probe
|
||
|
|
|
||
|
|
Commit 86e4cb35f2260374df4139c2352afe7fe247cb60 upstream.
|
||
|
|
|
||
|
|
usb_ehci_pdata is certainly required in ehci-platform driver.
|
||
|
|
This patch avoids using BUG_ON() from driver,
|
||
|
|
and return from probe with WARN_ON() if pdata was NULL.
