[PATCH 5.15 074/106] i2c: npcm7xx: Add check for platform_driver_register

[Greg Kroah-Hartman]

From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit 6ba12b56b9b844b83ed54fb7ed59fb0eb41e4045 ]

As platform_driver_register() could fail, it should be better
to deal with the return value in order to maintain the code
consisitency.
