Simplify error return if the code returns anyway. Other relevant changes: Replace devm_add_action() with devm_add_action_or_reset() This conversion was done automatically with coccinelle using the following semantic patches. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches - Replace devm_add_action() followed by failure action with devm_add_action_or_reset() - Replace 'goto l; ... l: return e;' with 'return e;' - Replace 'if (e) return e; return 0;' with 'return e;' Signed-off-by: Guenter Roeck <linux@roeck-us.net> --- drivers/input/touchscreen/raydium_i2c_ts.c | 18 ++++++------------ 1 file changed, 6 insertions(+), 12 deletions(-)
