ata: move ata_eh_analyze_ncq_error() & co. to libata-sata.c
* move ata_eh_analyze_ncq_error() and ata_eh_read_log_10h() to libata-sata.c * add static inline for ata_eh_analyze_ncq_error() for CONFIG_SATA_HOST=n case (link->sactive is non-zero only if NCQ commands are actually queued so empty function body is sufficient) Code size savings on m68k arch using (modified) atari_defconfig: text data bss dec hex filename before: 16164 18 0 16182 3f36 drivers/ata/libata-eh.o after: 15446 18 0 15464 3c68 drivers/ata/libata-eh.o Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
