mmc: core: use sysfs_emit() instead of sprintf()
In the Linux kernel, the following vulnerability has been resolved: mmc: core: use sysfs_emit() instead of sprintf() sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
