[PATCH V1 Resend 06/10] drivers: rtc: Drop (un)likely before IS_ERR(_OR_NULL)

[PATCH V1 Resend 06/10] drivers: rtc: Drop (un)likely before IS_ERR(_OR_NULL)

[Viresh Kumar]

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
is no need to do that again from its callers. Drop it.

gemini driver was using likely() for a failure case while the rtc driver
is getting registered. That looks wrong and it should really be
unlikely. But because we are killing all the unlikely() flags, lets kill
that too.

Hi Viresh,

Why are you resending?

[PATCH V1 Resend 06/10] drivers: rtc: Drop (un)likely before IS_ERR(_OR_NULL)

I never got a reply from Andrew Morton on V1, so resent it again. And
today Andrew asked me to take this via trivial tree.

So the resent.

I need to find a sane way to get few more people to the cover-letter.
The problem is that I am generating the cc-list with get_maintainers,
and if I combine that list for all the patches, it becomes huge. And
really can't send the cover-letter to those people then. Few lists may
block it as well, due to high number of cc'd people.

I am telling this because, the cover-letter did contain the reason for
resend.

The fact is that I sent you a mail yesterday stating that I applied that
particular patch.

Urg ..

I looked at the 'V1 Resend' series to see which all are applied, and
missed your reply on the first version.

Sorry about that.
