From: Sony Chacko <sony.chacko@qlogic.com>
Refactor 82xx driver to support new adapter - Qlogic 83XX CNA
Create mailbox based hardware interface mechanism
Seperate 82xx adapter hardware specific routines
Change register access macros:
QLCRD and QLCWR macros are used to access common registers.

The 'j' on the second line should be at the first column after the
openning parenthesis on the first line.

Same problem here.

And here.

This dev_info() call is indented one TAB too deeply.

Please remove this extraneous empty line.

This is improperly indented, function arguments split up into
subsequent lines should line up with the first column after
the openning parenthesis that they are a part of.
On the last line, there needs to be a space between the closing
parenthesis and the openning curly brace.
> + } else if ((mbx_err_code == QLCNIC_MBX_RSP_OK)

Incorrect indentation, and the "||" should appear at the end of the
first line rather than at the beginning of the second line.
> + mbx->req.arg[0] = (type | (mbx->req.num << 16) |
> + (adapter->ahw->fw_hal_version << 29));
This second line needs to be indented properly. If it makes the line too
long then split the expression up using temporary variables or create
a helper function so you can put the expression at a less deep indentation
level.
> + cmd.req.arg[1] = cpu_to_le32((mode ? 1 : 0) |
> + (adapter->recv_ctx->context_id) << 16);
This is not properly indented (and it's extremely tiring explaining
this same thing more than a dozen times during this review)
The first "(" on the second line must line up with the first column
after the openning parenthesis of cpu_to_le32( on the previous
line.
> + cmd.req.arg[1] = cpu_to_le32(1 |
> + adapter->recv_ctx->context_id << 16);
Same problem.
> + cmd.req.arg[1] = cpu_to_le32(2 |
> + adapter->recv_ctx->context_id << 16);
Same problem.
> + cmd.req.arg[1] = cpu_to_le32((mode ? (BIT_0 | BIT_1 | BIT_3) : 0) |
> + ((adapter->recv_ctx->context_id) << 16));
By some strange miracle you are able to get it correct in this case.
> + cmd.req.arg[1] = cpu_to_le32(op | (1 << 8) |
> + (adapter->recv_ctx->context_id << 16));
Again, same problem.
> + cmd.req.arg[2] = cpu_to_le32(coal->rx_packets |
> + (coal->rx_time_us << 16));
And here too.
> + cmd.req.arg[1] = cpu_to_le32(op | BIT_31 |
> + (func_id << 16));
And again.
> + for (i = 0, index = 2; i < max_ints; i++, index += 2) {
> +

Please remove this unnecessary blank line.

There is no need for two blank lines here, remove at least one of them.

I tired reviewing this driver just for coding style issues after just
looking at two or three of them.
I hope that it is no surprise to you that people are very reluctant to
review this driver at all, given how much basic stylistic issues
remain.
I haven't even begun to think about the actual technical semantics and
correctness of these patches. I doubt anyone else in the community
had either, and that won't even begin to happen until the coding style
issues are rectified.
You guys have a long, very long, way to go with this patch set.
