From 45586c7078d42b932c5399953d21746800083691 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 3 Feb 2020 17:37:45 -0800 Subject: treewide: remove redundant IS_ERR() before error code check 'PTR_ERR(p) == -E*' is a stronger condition than IS_ERR(p). Hence, IS_ERR(p) is unneeded. The semantic patch that generates this commit is as follows: // @@ expression ptr; constant error_code; @@ -IS_ERR(ptr) && (PTR_ERR(ptr) == - error_code) +PTR_ERR(ptr) == - error_code // Link: http://lkml.kernel.org/r/20200106045833.1725-1-masahiroy@kernel.org Signed-off-by: Masahiro Yamada Cc: Julia Lawall Acked-by: Stephen Boyd [drivers/clk/clk.c] Acked-by: Bartosz Golaszewski [GPIO] Acked-by: Wolfram Sang [drivers/i2c] Acked-by: Rafael J.
