[PATCH] backlight: ili922x: fix W=1 kernel-doc warnings

[Randy Dunlap]

Fix kernel-doc warnings found when using "W=1".

ili922x.c:85: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
ili922x.c:85: warning: missing initial short description on line:
 * START_BYTE(id, rs, rw)
ili922x.c:91: warning: contents before sections
ili922x.c:118: warning: expecting prototype for CHECK_FREQ_REG(spi_device s, spi_transfer x)(). Prototype was for CHECK_FREQ_REG() instead
