[PATCH v4 0/5] Improve user feedback in case of FPGA bitstream load failure

[vtpieter at gmail.com]

From: Pieter Van Trappen <pieter.van.trappen at cern.ch>

The main motivation for this patch series is to make the `fpga *`
commands' return message more explicit because simply returning the
command usage without indicating the root cause is not helpful.

In addition, the sandbox_defconfig was amended to facilitate compiling
fpga-based sources and various style, compiler errors and warnings
have been fixed.

v4:
 * make better use of prefixes in commit subjects
 * change patches' order to ensure no commit introduces compiler
 warnings or errors i.e. defconfig is now patch 5/5
 * add new patch 4/5 to remove compiler Werror=unused-function
 * add an additional Kconfig dependency to patch 2/5

v3: https://lore.kernel.org/all/20250626093519.115655-1-vtpieter@gmail.com/
 * enable FPGA configs in sandbox_defconfig instead of new one

v2: https://lore.kernel.org/all/20250626093519.115655-1-vtpieter@gmail.com/
 * use log_* instead of puts() which is now preferred
 * harmonize user feedback format; remove useless strings
 * add a sandbox_fpga_defconfig; amend fpga Kconfig
 * fix various compiler errors and warnings

v1: https://lore.kernel.org/all/20250626093519.115655-1-vtpieter@gmail.com/
