Subject: [PATCH] mwifiex: use del_timer variant in interrupt context
|
|
|
17e7d60 |
|
|
|
17e7d60 |
We might be in interrupt context at few places. So replace
|
|
|
17e7d60 |
del_timer_sync() with del_timer(). This patch fixes a kernel
|
|
|
17e7d60 |
trace problem seen occasionally during our testing.
