I don't see much value for this define. It is use once below so just or
it there. That way you can "directly" see what is written to the register.

just use 'CY_4373_F2_WATERMARK | SBSDIO_MESBUSYCTRL_ENAB' here. No
braces needed.
Thanks for the input. The biggest difference is to prevent a 4-line
function call like below so it's more readable. I'll make this change in
V2. Please let me know if below looks too messy then I'll move back to V1:
brcmf_sdiod_writeb(sdiod, CY_4373_F2_WATERMARK |
SBSDIO_MESBUSYCTRL_ENAB,
CY_4373_F2_WATERMARK |
SBSDIO_MESBUSYCTRL_ENAB, &err);
The second argument should just be SBSDIO_FUNC1_MESBUSYCTRL so that will
make it a bit less messy. Look okay to me.
