Series: fbdev: au1100fb: support COMPILE_TEST and fix multi-device
       support and other cleanups
Author: Uwe Kleine-Koenig <u.kleine-koenig@baylibre.com>

This is a 7 patch cleanup series for the au1100fb fbdev driver, moving
global data into per-device structures, adding COMPILE_TEST support,
converting printk wrappers to pr_*, folding the header file into the
.c file, and replacing the license boilerplate with SPDX.

Two minor issues found.

Patch 5/7 - fbdev: au1100fb: Replace custom printk wrappers by pr_*

> diff --git a/drivers/video/fbdev/au1100fb.c b/drivers/video/fbdev/au1100fb.c
> index 782f70c3a98f..86aafa4f0966 100644

[ ... ]

> +#define pr_fmt(fmt) "au1100fb:" fmt "\n"

The old print_err/print_warn/print_info macros used DRIVER_NAME ": "
(with a space after the colon), e.g.:

    printk(KERN_ERR DRIVER_NAME ": " f "\n", ## arg)

The new pr_fmt omits the space, so all messages change from
"au1100fb: some message" to "au1100fb:some message".

Should this be "au1100fb: " fmt "\n" to preserve the original
formatting?


Patch 6/7 - fbdev: au1100fb: Fold au1100fb.h into its only user

> diff --git a/drivers/video/au1100fb.c b/drivers/video/au1100fb.c
> new file mode 100644
> index 000000000000..e69de29bb2d1

This creates an empty file at drivers/video/au1100fb.c (note: not in
the fbdev/ subdirectory). Was this file included by accident?

FINAL REGRESSIONS FOUND: 2

False positives eliminated:
- Considered whether the compound literal initialization ordering in Patch 1 could cause uninitialized field access -- verified field assignment order is equivalent to original
- Considered whether `pr_devel` behavior changed with `#define DEBUG 0` removal -- verified `pr_devel` compiles out when DEBUG is not defined, matching old behavior
- Considered whether `#ifndef CONFIG_S390` in Patch 4 could cause issues on MIPS -- verified CONFIG_S390 is never set on MIPS
- Considered whether the `%pad` format specifier in Patch 3 adds a duplicate `0x` prefix -- verified `%pad` prints hex digits without prefix

### Task 5: AI authorship estimate

AI-authorship-score: low

The series shows typical human authorship patterns: it addresses a real-world problem (COMPILE_TEST support) for a legacy driver, includes incremental v1-v4 iteration with specific version notes referencing reviewer feedback, uses personal coding conventions, and demonstrates domain-specific knowledge of MIPS memory mapping (KSEG1ADDR, CCA bits).

### Task 6: Issue severity

issue-severity-score: low

Both issues are cosmetic/cleanup: a missing space in log message prefix and an accidentally created empty file. Neither has any functional impact on the driver's behavior.

FINAL TOKENS USED: ~45000
