Re: [PATCH V1] scsi: ufs: Get boot device storage type from command line

Hi Brat,

Thanks for you response!

Yes, since SCSI_UFSHCD=y am selecting UFS_QCOM_CMDLINE=y so that it gets 
__setup() declarations. I am able to read the command line arguments and 
get this "androidboot.bootdevice=" info. I had cross checked again.

Thanks,
Chetan C R
