Andrew Jeffery 9b5fcb15be fsi: core: Fix small accesses and unaligned offsets via sysfs ... [ Upstream commit 9f4c2b516b ] Subtracting the offset delta from four-byte alignment lead to wrapping of the requested length where `count` is less than `off`. Generalise the length handling to enable and optimise aligned access sizes for all offset and size combinations. The new formula produces the following results for given offset and count values: offset count | length --------------+------- 0 1 | 1 0 2 | 2 0 3 | 2 0 4 | 4 0 5 | 4 1 1 | 1 1 2 | 1 1 3 | 1 1 4 | 1 1 5 | 1 2 1 | 1 2 2 | 2 2 3 | 2 2 4 | 2 2 5 | 2 3 1 | 1 3 2 | 1 3 3 | 1 3 4 | 1 3 5 | 1 We might need something like this for the cfam chardevs as well, for example we don't currently implement any alignment restrictions / handling in the hardware master driver.
