[dpdk-stable] [PATCH v2] drivers/crypto: fix build with make 4.3

[Thomas Monjalon]

28/02/2020 14:25, Thomas Monjalon:
> In the check for the version of intel-ipsec-mb library,
> there is a backslash in front of the #include.
> This backslash is for escaping the hash sign parsed as
> a number sign in make.
> 
> Since make-4.3, escaping is not required for the number sign.
> As a consequence, it resolves now to '\#':
> 
> syntax error near unexpected token `|'
> `grep -e "IMB_VERSION_STR" \#include <intel-ipsec-mb.h> | cut -d'"' -f2'
> syntax error near unexpected token `|'
> `grep -e "IMB_VERSION_NUM" \#include <intel-ipsec-mb.h> | cut -d' ' -f3'
> 
> The makefiles are fixed by using a variable for the hash sign,
> as recommended in make-4.3 changelog:
> 	https://lists.gnu.org/archive/html/info-gnu/2020-01/msg00004.html

I was expecting some reviews and a merge in the crypto tree.
Given it is blocking me to merge any other patch,
after waiting 2 weeks,
Applied in master branch.
