Re: [alsa-devel] [PATCH] treewide: remove redundent IS_ERR() before error code check

pon., 6 sty 2020 o 06:00 Masahiro Yamada masahiroy@kernel.org napisał(a):

'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>
