patches: add c5 (STANDARD_FACTORY_EFUSE_FLAG=n) to the series

Regenerates patches/ as a proper series off marfrit/bes2600-dkms:mobian:

  0001-bes2600-use-request_firmware-for-factory.txt-read.patch  (c1)
  0002-bes2600-default-STANDARD_FACTORY_EFUSE_FLAG-off-for-.patch (c5)

c5 covers two changes in a single commit:

  - Makefile: STANDARD_FACTORY_EFUSE_FLAG default flip from y to n
    (the PineTab2 shipped factory.txt has no ##select_efuse_flag
    section, so the driver was expecting 31 sscanf fields and failing
    on the 30-field file).

  - wsm.h: drop the #if defined(STANDARD_FACTORY_EFUSE_FLAG) guard
    around the wsm_save_factory_txt_to_mcu() prototype. The function
    definition in wsm.c and the call site in sta.c were always ungated,
    so with the new flag default gcc -Werror=missing-prototypes would
    otherwise break the build.

Both patches verified on PineTab2 (BES2600WM + RK3566) running
linux-pinetab2 6.19.10-danctnix1-1: post-reboot dmesg no longer shows
the factory-read or factory-parse error sequence.

+Subject: [PATCH 2/2] bes2600: default STANDARD_FACTORY_EFUSE_FLAG off for
+ PineTab2 factory.txt format
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The shipped factory calibration file bes2600_factory.txt on PineTab2
+(danctnix linux-firmware 0.3.5_2023.0209) contains 30 calibration
+fields: head (3), iq/xtal (3), 2.4G power 11n (5), 5G power 11n (15),
+bt (4). The file terminates with '%%\n' directly after edr_power.
+
+When STANDARD_FACTORY_EFUSE_FLAG is defined at compile time the driver
+assembles STANDARD_FACTORY with an extra select_efuse_flag section
+appended and expects 31 sscanf matches (FACTORY_MEMBER_NUM=31):
+
+    __STANDARD_FACTORY + \"##select_efuse_flag\\nselect_efuse:%hx\\n\"
+                      + \"%%%%\\n\"
+
+The PineTab2 factory.txt has no select_efuse_flag section, so sscanf
+stops after field 30 and factory_parse() returns -1 with:
+
+    bes2600_factory.txt parse fail
+    read and check bes2600/bes2600_factory.txt error
+    factory cali data get failed.
+
+This was latent until the preceding patch (use request_firmware() for
+factory.txt read) fixed the path bug that masked the parse failure.
+
+Default STANDARD_FACTORY_EFUSE_FLAG to n. The flag remains overridable
+at build time (make STANDARD_FACTORY_EFUSE_FLAG=y ...) for chips /
+firmware packages that do ship the select_efuse_flag section.
+
+Also: the wsm_save_factory_txt_to_mcu() prototype in wsm.h was
+inconsistently wrapped in a conditional that keyed on
+STANDARD_FACTORY_EFUSE_FLAG, but the function definition in wsm.c and
+the call site in sta.c are ungated. With the flag now defaulting to
+n, the gcc -Werror=missing-prototypes flag breaks the build. Drop the
+conditional wrapper around the prototype — the function exists and is
+used regardless of the factory-parse flag.
+
+Tested-on: PineTab2 (BES2600WM + RK3566) running linux-pinetab2
+6.19.10-danctnix1-1. With the flag defaulted off, factory_parse()
+succeeds on the shipped factory.txt, factory_cali_data is populated,
+and dmesg no longer shows the parse-fail / read-and-check-error /
+factory-cali-data-get-failed sequence.
