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);
