drm/tinydrm: mipi-dbi: Silence: ‘cmd’ may be used uninitialized
Fix this warning: drivers/gpu/drm/tinydrm/mipi-dbi.c: In function ‘mipi_dbi_debugfs_command_write’: drivers/gpu/drm/tinydrm/mipi-dbi.c:905:8: warning: ‘cmd’ may be used uninitialized in this function [-Wmaybe-uninitialized] ret = mipi_dbi_command_buf(mipi, cmd, parameters, i); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cmd can't be used uninitialized, but to satisfy the compiler, initialize it to zero.
