      crypto: caam/qi - fix error handling in ERN handler · 51fab3d7
      由 Horia Geantă 提交于 
      ERN handler calls the caam/qi frontend "done" callback with a status
of -EIO. This is incorrect, since the callback expects a status value
meaningful for the crypto engine - hence the cryptic messages
like the one below:
platform caam_qi: 15: unknown error source

Fix this by providing the callback with:
-the status returned by the crypto engine (fd[status]) in case
it contains an error, OR
-a QI "No error" code otherwise; this will trigger the message:
platform caam_qi: 50000000: Queue Manager Interface: No error
which is fine, since QMan driver provides details about the cause of
failure

      crypto: drivers - Remove dev_err() usage after platform_get_irq() · 514838e9
      由 Stephen Boyd 提交于 
      We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )

-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }

-dev_err(...);
)

}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).

      由 Horia Geantă 提交于 
      IV transfer from ofifo to class2 (set up at [29][30]) is not guaranteed
to be scheduled before the data transfer from ofifo to external memory
(set up at [38]:

[35] 28000010    seqfifold: skip len=16
[36] A8080A04         math: (seqin + math0)->vseqin len=4

[38] 69300000   seqfifostr: msg len=vseqoutsz
[39] 5C20000C      seqstr: ccb2 ctx len=12 offs=0

If ofifo -> external memory transfer happens first, DECO will hang
(issuing a Watchdog Timeout error, if WDOG is enabled) waiting for
data availability in ofifo for the ofifo -> c2 ififo transfer.

Make sure IV transfer happens first by waiting for all CAAM internal
transfers to end before starting payload transfer.

New descriptor with jump command inserted at [37]:

[Note: the issue is present in the descriptor from the very beginning
(cf. Fixes tag). However I've marked it v4.19+ since it's the oldest
maintained kernel that the patch applies clean against.]
