Subject: opkg: fix stray \ warnings with grep-3.8
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eb1b0220439262d6fff2a2e2180b87db27390905;p=openwrt%2Fstaging%2Fblocktrron.git

opkg: fix stray \ warnings with grep-3.8

We simply grep for "src/". So no need for "\/".
Furthermore, since grep-3.8 this creates warnings.

As written in the grep-3.8 announcement:
  Regular expressions with stray backslashes now cause warnings, as
  their unspecified behavior can lead to unexpected results.
  For example, '\a' and 'a' are not always equivalent
  <https://bugs.gnu.org/39678>.

Fixes a warning during the first boot:
  grep: warning: stray \ before /
