Share the contained code where possible. There is already , which implements generic (as in 'empty') functions of the fbdev helpers. The header was added in commit aafe4dbed0bf ("asm-generic: add generic versions of common headers"), but never used. Each per-architecture header file declares and/or implements fbdev helpers and defines a preprocessor token for each. The generic header then provides the remaining helpers. It works like the I/O helpers in . For PARISC, the architecture helpers are mixed up with helpers for the system's STI graphics firmware. We first move the STI code to appropriate locations under video/ and then move the architecture helper under arch/parisc. For Sparc, there's an additional patch that moves the implementation from the header into a source file. This allows to avoid some include statements in the header file.
