mmc: sdhci: Fix a potential uninitialized variable
Smatch complains that "ret" can be used without being initialized. drivers/mmc/host/sdhci.c 4383 if (!IS_ERR(mmc->supply.vqmmc)) { 4384 if (enable_vqmmc) { ^^^^^^^^^^^^ 4385 ret = regulator_enable(mmc->supply.vqmmc); ^^^^^ 4386 host->sdhci_core_to_disable_vqmmc = !ret; 4387 } "ret" is only initialized when "enable_vqmmc" is true.
