[ Upstream commit 328bda09cc91b3d93bc64f4a4dadc44313dd8140 ]
GCC 13 complains about the truncated output of snprintf():
drivers/mmc/host/mmc_spi.c: In function ‘mmc_spi_response_get’:
drivers/mmc/host/mmc_spi.c:227:64: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=]
227 | snprintf(tag, sizeof(tag), " ... CMD%d response SPI_%s",
| ^
drivers/mmc/host/mmc_spi.c:227:9: note: ‘snprintf’ output between 26 and 43 bytes into a destination of size 32
227 | snprintf(tag, sizeof(tag), " ... CMD%d response SPI_%s",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
228 | cmd->opcode, maptype(cmd));
Drop it and fold the string it generates into the only place where it's
emitted - the dev_dbg() call at the end of the function.
