Subject: ide: add PC_FLAG_ZIP_DRIVE pc flag
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5d41893c0f9caf94b449eada0279a08c86f0212e;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ide: add PC_FLAG_ZIP_DRIVE pc flag

Add PC_FLAG_ZIP_DRIVE pc flag, set it in idefloppy_do_request()
and check for it (instead of checking for IDEFLOPPY_FLAG_ZIP_DRIVE)
in idefloppy_transfer_pc().  This is a preparation for adding
generic ide_transfer_pc() helper.

There should be no functional changes caused by this patch.
