Subject: kconfig: make conf_unsaved a local variable of conf_read()
X-Git-Url: https://jxself.org/git/?p=carl9170fw.git;a=commitdiff_plain;h=04272dbc3dfed9d035a6359ff85101cddcd26bde

kconfig: make conf_unsaved a local variable of conf_read()

conf_unsaved is initialized by conf_read_simple(), but it is possible
to move it to conf_read() so that it can be a local variable.
