From: Jiangshan Yi <yijiangshan at kylinos.cn>

Fix the following coccicheck warning:

drivers/base/component.c:544: WARNING opportunity for min().
drivers/base/component.c:740: WARNING opportunity for min().

min() macro is defined in include/linux/minmax.h. It avoids
multiple evaluations of the arguments when non-constant and performs
strict type-checking.
