There is an error building when
Compiler version: gcc (GCC) 14.3.0
Assembler version: GNU assembler (GNU Binutils) 2.44

Error log:
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/arm/probes/kprobes/test-kprobes.o
ERROR: modpost: "__ffsdi2" [drivers/spi/spi-amlogic-spifc-a4.ko] undefined!

Use __ffs API instead of __bf_shf to be safer.

Currently a call to regmap_write is not being error checked because the
return checke is being performed on the variable ret and this variable
is not assigned the return value from the regmap_write call. Fix this
by adding in the missing assignment.

This driver provides support for the SPI mode of the Amlogic
Flash Controller. It supports both SPI NOR flash and SPI NAND
flash. For SPI NAND, the Host ECC hardware engine can be enabled.
The controller implements the SPI-MEM interface and does not
support generic SPI.
