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: // <smpl> @@ expression ptr; constant error_code; @@ -IS_ERR(ptr) && (PTR_ERR(ptr) == - error_code) +PTR_ERR(ptr) == - error_code // </smpl> Link: http://lkml.kernel.org/r/20200106045833.1725-1-masahiroy@kernel.org Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Cc: Julia Lawall <julia.lawall@lip6.fr> Acked-by: Stephen Boyd <sboyd@kernel.org> [drivers/clk/clk.c] Acked-by: Bartosz Golaszewski <bgolaszewski@baylibre.com> [GPIO] Acked-by: Wolfram Sang <wsa@the-dreams.de> [drivers/i2c] Acked-by: Rafael J.
