From: Andy Shevchenko Date: Mon, 25 Aug 2025 16:32:56 +0000 (+0200) Subject: floppy: Replace custom SZ_64K constant X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=8e7ee0f6fa33934373c1c37e8cfb71cff2acea09;p=users%2Fjedix%2Flinux-maple.git floppy: Replace custom SZ_64K constant There are only two headers using the K_64 custom constant. Moreover, its usage tangles a code because the constant is defined in the C file, while users are in the headers. Replace it with well defined SZ_64K from sizes.h.
