The first patch just fixes a couple coding style issues. The second removes a couple unnecessary switches. Last three refactor the read/write_regs functions to avoid if-elses by using function pointers to smaller, specialized routines. Tested with pca9534 and pca9535 chips. v1 -> v2: - constified the offset structures in patch 2/5 v2 -> v3: - modified the order of the patches so that minor coding style fixes no longer create noise for the later changes - moved the **_write_regs_16() assignments to where other variants are assigned Bartosz Golaszewski (5): gpio: pca953x: code shrink gpio: pca953x: refactor pca953x_write_regs() gpio: pca953x: refactor pca953x_read_regs() gpio: pca953x: remove an unused variable gpio: pca953x: coding style fixes drivers/gpio/gpio-pca953x.c | 268 ++++++++++++++++++++++---------------------- 1 file changed, 134 insertions(+), 134 deletions(-) -- 2.7.4
