ipq40xx: 5.15: add patch commenting unused sdhci function
Add patch commenting unused sdhci function, hopin this will be dropped when the problem is actually found. Fix compilation warning: drivers/mmc/host/sdhci-msm.c:1781:13: error: 'sdhci_msm_set_clock' defined but not used [-Werror=unused-function] 1781 | static void sdhci_msm_set_clock(struct sdhci_host *host, unsigned int clock) | ^~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

+Subject: [PATCH] mmc: sdhci-msm: comment unused sdhci_msm_set_clock
+
+comment unused sdhci_msm_set_clock and __sdhci_msm_set_clock as due to some
+current problem, we are forced to use sdhci_set_clock.
