commit 46109648052fe778c75f199d72255c899578d6f7 upstream.
Export spi_mem_default_supports_op(), so that controller drivers
can use this.
spi-mem driver already exports this using EXPORT_SYMBOL,
but not declared it in spi-mem.h.
This patch declares spi_mem_default_supports_op() in spi-mem.h and
also removes the static from the function prototype.
This patch also squashes upstream commit 72e6841608b9 ("spi: spi-mem: Fix
build error without CONFIG_SPI_MEM")' in the current patch as commit
46109648052f ("spi: spi-mem: export spi_mem_default_supports_op()")'
introduced below build error when built without CONFIG_SPI_MEM:
drivers/spi/spi-zynq-qspi.o: In function `zynq_qspi_supports_op':
spi-zynq-qspi.c:(.text+0x1da): undefined reference to `spi_mem_default_supports_op'
