Subject: [PATCH] backlight: ili922x: fix kernel-doc warnings
Date:   Thu, 12 Jan 2023 22:41:08 -0800

Convert comments for START_BYTE() and CHECK_FREQ_REG() macros into
kernel-doc notation to avoid these kernel-doc warnings:

drivers/video/backlight/ili922x.c:85: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * START_BYTE(id, rs, rw)
drivers/video/backlight/ili922x.c:118: warning: expecting prototype for CHECK_FREQ_REG(spi_device s, spi_transfer x)(). Prototype was for CHECK_FREQ_REG() instead
