SD_ROCR_S18A is already defined
and is used to check the rocr value as shown below.

So, replace with already defined values for readability.

--------------------------------------------------
/sd.h
.#define SD_OCR_S18R    (1 << 24)    /* 1.8V switching request */
.#define SD_ROCR_S18A   SD_OCR_S18R  /* 1.8V switching accepted by card */

/sd.c
static int mmc_sd_init_card(struct mmc_host *host, u32 ocr,
	struct mmc_card *oldcard)
{
...
        if (rocr & SD_ROCR_S18A && mmc_host_uhs(host)) {
                err = mmc_sd_init_uhs_card(card);
}
-------------------------------------------------

Applied for next, thanks!

Next time, please use a proper patch prefix ("mmc: core:" in this case).

Kind regards
Uffe
