Subject: [PATCH] fix-scard-stop-on-resume.patch
|
||
|
|
Reported-by: Ville-Pekka Vainio <vpivaini@cs.helsinki.fi>
|
||
|
|
|
||
|
|
The reporter noticed SD Card clock is running again after resume. After
|
||
|
|
looking at the code I saw I missed two tricks, this will force it off
|
||
|
|
after resume and will do better generally depending on what the last SD Card
|
||
|
|
packet was.
|
||
|
|
|
||
|
|
Since bulk read packet is normally last action (which set the clock off even
|
||
|
|
without this) the old patch worked for normal cases. But after resume, the last
|
||
|
|
packet on the wire was not a bulk transfer and we didn't take care about the
|
||
|
|
clock then.
